10 Most Common Reasons for Computer Failure in Business and Industry

Yunan — Sun, 05 Sep 2010 07:08:35 +0000

Computers are performing more and more tasks in the office and workplace than they ever have before. Computers can conduct many tasks more efficiently than human workers but the more we rely on them the more vulnerable we find ourselves when the machines fail.

Each year, companies have an average of 501 hours of computer downtime, costing them millions in annual productivity and revenue and according to a recent study; computer downtime is responsible for the loss of 3.6% of annual revenue. Which is almost has high as the revenue loss by employee absence (6 %)!

The average life of an office PC is 3-4 years yet a computer’s life can be cut down to a fraction of that amount if the machine is expected to work in less than perfect conditions.

Yet the majority of causes for a computer failure can be prevented by adhering to some simple steps:

1. User errors – Any tool is only as good as the workman who uses it and computers are no different. Actions such as not powering down properly, skipping scan disks or continual button pushing while a computer is processing can damage a computer’s hardware, particularly drives and processors. Always follow the correct guidance in using a computer machine.

2. Faulty manufacture –It seems there are an almost infinite number of manufacturers and assemblers making computers and while some have vast experience and resources, others are no more than two guys in a garage so it is not surprising that an increasing number of computer systems are faulty when bought.

3. Bad upgrades – It is not just computers themselves that are victims of bad workmanship, upgrades by inexperienced computer fitters can cause horrendous problems. Faulty add-ons such as RAM can kill a processor instantly, also attempting to ‘overclock’ or interfere with a processor can often lead to a fatal melt-down.

4. USB Device Mishaps. It seems everything can be plugged into a USB these days. However, it maybe that your USB device is not suited to the operating system you use or it may be faulty leading to a fatal short circuit.

5. Power problems – Power surges or unexpected power cuts can not only cause instant loss of data but can fry a processor. It is not just power from the grid that causes problems either – lightning can surge through cables (even phone wires) frazzling your system and so can static.

6. Dirt/Dust. A dusty environment will clog a computer and block cooling vents causing a computer to overheat. Dust can also contain conductive material and particles can stick to circuit boards and cause a short circuit. A cloud of dust can also explode if it comes into contact with a source of ignition (like a computer). Even home computers if not properly cleaned can succumb to problems caused by too much dust.

7. Water/fluids. Of course computers are electrical and with all electrical equipment, computers and water do not mix, just one spilt cup of coffee could see the end of your PC.

8. Heat. Processors can run exceptionally hot and if a computers cooling system is inadequate (because the machine has been upgraded, overclocked or just clogged up with dust and grime) it will only be a matter of time before it packs up for good.

9. Cold. Just as with heat, computers don’t enjoy the cold too much either. Processors will not operate at all if the operating temperature is too cold as condensation inside the machine can freeze and expand damaging the processor and electronics.

10. Knocks/bangs. Computers are sensitive machines, simply moving a PC to another room can cause havoc, disrupting the delicate circuitry and hard drives. Dropping a computer or severe knocks and bangs will permanently damage the circuits and processors or dislodge wiring.

The easiest way to protect a PC in business applications from uncontrollable hazards such as heat, dust or vibrations is to use an industrial computer enclosure. These industrial PC enclosures allow a conventional PC to be used whilst housed in a protective cocoon which can be dust, water and even explosive proof.

What Computer Should I Buy? Dell, Hp,acer – There are so Many Choices!!

Yunan — Tue, 31 Aug 2010 07:10:50 +0000

I own a computer consulting business. I have been working with computers for the last 16 years. The most common question that I get from many of my home user customers is “What computer should I buy?” There are so many different configurations and choices when you go to purchase a computer that it makes it difficult unless you know what the computer parts are, even then you still have many different choices. Most people just want to purchase computer quickly and would rather that someone just help them pick the one that would best suit their needs without trying to learn about all of the details. I can certainly understand that. For example, I personally don’t want to know the details about how my plumbing works. I would just like the plumber to fix the problem or do what is needed without hassling me with the details. But then you have that issue with being able to trust what someone is recommending you purchase. Is it really a good deal and is the sales person really recommending the best computer for your needs. Most of the sales people I have to believe are doing their very best to help you make the correct choice but it is better that you understand some of the basic details/components about the computer that you are getting ready to purchase to make the sales persons job easier and to better understand what the options are for you when you are shopping around.

So let’s get right to it:

1. The Processor or CPU (Central Processing Unit) – This is the driving force or you could say heart in your computer. It also acts as a traffic cop to the data being processed. So the faster it is the faster data can be processed. I always recommend that you everyone purchase one or two steps up from the least available if I am custom building a computer on the Dell Site or HP’s site. If you will go to one of these sites and click on one of the computers to custom build it you will see the options that I talking about.

2. RAM or Memory – Some people get this confused with Hard Drive space. Hard Drive space is a totally separate thing and you should have much more of it. Think of RAM or Memory as your desktop or temporary storage. The bigger your desktop the more room that you will have to layout papers to view without getting up from your chair so the more RAM or Memory that you have the better but it gets expensive if you go over the mid point offered. For example at this time the mid point for most PC’s would be around 2GB of RAM or Memory. I would suggest a minimum of at least 1GB for most applications but if you are doing something like graphic/image editing applications or playing games you could need more. You should check the application that you think would be most demanding or graphical to determine what the minimum amount of RAM or Memory is recommended and I would then get more than the recommended amount for improved performance.

3. Hard Drive – This is the device that actually stores your data when you save it. Think of it as your filing cabinet or permanent storage (at least until you delete it) . You will need to determine what you will be using your computer for. For example if you will be using your computer mainly to surf the internet and save Microsoft Word Documents you probably will not need over the standard drive size (for example at the time of this writing – 80GB or 160GB is standard depending on the type/model of computer you purchase) but if you want to purchase music, save photos, or will be doing a lot of image editing on your computer you may want to invest in a bigger hard drive (for example – 250GB) or you can always get an external drive to store your work on.

4. CD/CD-RW/DVD/DVD-R/DVD-RW – What more choices?? These are CD drive choices of today and of course there is Blue-Ray which I would only recommend if you are really into burning CD’s and chances are if you are reading this you will not need that technology but you can always Google “Blue-Ray” to find out more about it if you think that you would be interested. I would recommend that you purchase the best that you can afford regarding CD drives. Below is a quick run down of what each will allow you to do:

CD – Read-only CD’s – installs most programs with the exception of programs that come on DVD discs.

DVD – Read-only CD’s and DVD’s – this would at least allow you to read/install programs from DVD disc and play DVD movies.

CD-R – Allows you to install programs from CD’s, create CD’s for music/data – you can only write to CD-R CD’s which means that you can only write to the CD once.

CD-RW – Allows you to install programs from CD’s, create CD’s for music/data/rewrite to CD-RW disc but you can only write once to CD-R disc still.

DVD-R – Allows you to install programs from CD/DVD disc, create CD-R/DVD-R CD/DVD’s for music/data/videos. You can only write once to the disc.

DVD-RW – Allows you to install programs from CD/DVD disc, create CD-R/DVD-R/CD-RW/DVD-RW CD/DVD’s for music/data/videos. You can rewrite to CD-RW or DVD-RW discs.

5. Do I need a floppy disk? Most people wouldn’t really need this option any more since most programs come on CD’s or DVD’s these days.

6. Video Card – This is the device that you will connect your monitor to. Most of the time you can just take the standard video card but if you intend on modified photos or playing games you may want to invest in a better video card – keep in mind that video cards also have memory so the more memory the better here also.

7. Operating Systems – Honestly at the time of this writing I prefer Windows XP Pro SP2 since there are still some issues with Windows Vista even with SP1 at this time. For example there are some issues with software and printers. If you purchase a computer from the link that I give you below you can choose to purchase most of the computers with Windows XP Pro SP2 still. Most of the computers in the store’s today will have the Windows Vista Home operating system on them. It will work and if you are just going to use the latest programs, devices and search the internet this may be the operating system that will work for you.

8. Last but not least would be that you will for sure need some type of antivirus. I would highly recommend purchasing Symantec Internet Security and understand that you must pay for the subscription each year or pay for a 24/36 month subscription in order to keep getting updates. I have so many times worked on peoples computers where their antivirus had ran out and they had gotten viruses. They didn’t even know that it had ran out because they forgot that they must update it or it seemed unimportant then I get a call because their computer is infested with pop-ups, etc.

Here are some links that are helpful if you would like to view my recommendations:

Dell Hot Offers

www.hp.com

I would highly recommend a Dell OptiPlex for PC’s or Latitude for a laptop. You can go through the Dell Hot Offers to get the best deals. The reason that I would suggest these models is that these models have a standard 3 year warranty and these are the models that are standard for business. What is the advantage? Well, the parts that would be in these model of computers would have been through the testing process and should be more reliable. For example the Inspiron, XPS, and Vistro may have later technology but that is just it these computers are more stable for business use. I can’t say that you would have any problems with the Inspiron, XPS, Vistro, or any other brand of PC that you would buy but I am just saying that the Optiplex and Latitude seem to me to be a better computer. If you want some of the later technology (for example built-in SD, Micro SD card readers, capability to watch TV from your computer, etc.) I would recommend purchasing something like the XPS or Vistro.

One more very important thing is to get the media for the operating system with the computer that you purchase or make the restore disc as soon as you get the computer since it would be necessary if you have to restore your system to factory default later.

Here is an example of a standard PC that I would have setup for a customer (remember that this is as of 04/07/2008 – in other words the prices change regularly but this will give you an idea):

Optiplex 330 MiniTower

Starting Price $1282

Instant Savings $352

SubTotal $930

This would include the following:

Intel Core 2 Duo Processor E4500 (2.2GHz, 2M, 3322T – Processor

Geniune Windows XP Pro SP2 with media Operating System

2GB DDR2 Non-ECC SDRAM, 667MHZ (2 DIMM) RAM or Memory

160GB High Reliability SATA 3.0 GB/s and 8MN Databurst Cache – Hard Drive

16X DVD-ROM SATA, Cyberlink Power DVD DVD Drive

Dell 20 inch E207FP Widescreen Flat Panel, Analog

Internal Speaker At least get the internal speaker so that you can hear the computer if you receive a beep or error

Standard Keyboard

Standard Mouse I would suggest that you purchase an optical mouse.

Microsoft Office Basic and Adobe Standard This was an additional $150 so if you don’t need it you can use OpenOffice.org to do the same thing and it is FREE

Norton Internet Security 36 month subscription If you want to use something free you can use AVG Free but I would recommend Norton over AVG personally

3 year warranty This is a standard warranty for this model computer

As I said this is as of 04/07/08 and the price I am certain will be different when you view this product and there may be even a different model number but the Optiplex and Latitude models should be available.

I hope that this does help someone out there and makes it clearer when you go to purchase a computer what you need to be looking for.

Do You Have a Slow Computer? Fix it Today Totally For FREE!

Yunan — Thu, 26 Aug 2010 07:11:00 +0000

Having a slow computer can really cause someone terrible stress in this age of technological dependence. There are so many things that can only be accomplished through the services of a computer that works at high speed, including the fast completion of important office documents or school assignments, Internet-based research, and other use of computer programs and applications. If you have a computer that runs painfully slow, it’s understandable why you should feel frustrated. Thus, having your computer repaired as soon as possible is essential.

However, having your computer professionally fixed can be costly – and you can end up feeling even more frustrated with the huge amount you need to shell out just to have your computer running fast again. The good news is that you can fix your slow computer totally free of charge today, all on your own and without expensive assistance. All you have to do is read on.

One of the prime suspects in the presence of speed problems in a computer is chaos in the registry. The registry acts as the thinking tool of the computer, which means that it houses all the files that a computer has and organizes these files in order to make the computer meet the requests or commands of the user. If your registry is full to the brim, your computer would most definitely have difficulty managing the files efficiently and quickly. In order to solve slow computer problems, it is important that you keep your registry properly fixed using a tried and tested registry cleaner program or software.

Aside from the use of a proven program or software to clean out your registry, you also need to check other parts of your computer that also house files, particularly your recycling bin and your temporary files folder. It is a common misconception among users that once they delete a file, said file immediately gets removed from their computer system. On the contrary, the file is only transferred to another area, which is nowhere else than the recycling bin. The presence of too many files slows down a computer’s performance, so it is a must that the recycling bin be emptied not just once but on a regular basis. Meanwhile, the temporary files folder houses the Internet browser’s history and cache. Just like the recycling bin, the temporary files folder can get full if left ignored. Emptying it every now and then can reduce incidents of slow computer problems.

Computer files can really wreak havoc on a computer system. Sometimes, files wander around the hard drive and hide themselves in random folders where they do not belong. In order to solve this particular problem and deal away with a slow computer, performing def ragging on the hard drive is vital. A simple but thorough def ragging arranges your files and puts them in their proper locations. Defragmentation is actually one of the most basic things that a user should do to ensure top-speed performance of his or her computer.

You don’t need to spend a fortune on computer repairs if you have a slow computer. With a few tricks up your sleeve, like the ones you just read, you can solve your computer’s speed problems in no time and with no repair expenses.

Does registry software really make your computer run faster? 97% say it makes their computers run 10 times faster. Learn how and get your FREE Registry Cleaner download today at www.Registry-Cleaners-Exposed.com and fix your slow computer problems.

6 Tips to Fix A Slow Computer – In Under 2 Minutes

Yunan — Wed, 11 Aug 2010 07:12:52 +0000

1. Go Easy On The Display Settings
It is very easy to get carried away with a wide range of visual options. While you might things that this makes your pc look good – it will also impact on the performance of your computer. If you get rid of some of those display options you will enjoy a computer that is faster and more reliable.

So how do you fix a slow computer by changing the visual display settings?

Find the control panel on your computer and click the system option. Go to the advanced tab. In the performance tab click on the settings. OK now you will see a wide range of options that can be selected. I would remove all and only leave the following as selected items. Show shadows under menus, Show shadows under mouse pointer, Show translucent selection rectangle, Use drop shadows for icons labels on the desktop, Use visual styles on windows and buttons

Try out these different options and work out what is best for you. The main thing is to make sure you do not have too many options as it will make your computer slower.

2. Remove File Indexing
You may not have heard of file indexing before – but enabling this option on your computer will slow your computers performance markedly. It uses a large volume of the RAM (Memory) on your computer. So – we suggest you disable this service and you will notice the difference immediately.
If you go to ‘my computer’ and right click the C: drive. Then select properties and unselect the “allow indexing service to index this disk for fast file searching”. Then apply this change to C: subfolders and files and click OK

3. Get Rid of Your Desktop Picture
I know you quite like the picture of aunt Dorothy that you have on your computer desktop background! However, if you get rid of this image and restore default settings for your background you will improve your computer speed and performance. You are using a lot of memory to have this on your computer background.

4. Clean Your Computer Registry
Your computer registry is the powerhouse of your computer. If your windows registry is not free from damage and well organized, your system will become unbelievably slow and is likely to start freezing, and crashing. You should regularly clean your windows registry with and effective registry cleaning product to ensure that you computer is running fast and your registry is performing optimally. Visit www.fixaslowcomputer.com for details on top rated registry products and to perform a free scan of your computer registry to see if it is running at peak performance.

5. Clear your computers ‘prefetch’ folder
What is ‘pre-fetching’? Well – this actually refers to when your computer will pre-load frequently loaded applications and data to ensure that your programmes start running faster than without prefetching. However, after you have used your computer for a period of time it will keep loading some stuff that is no longer necessary. You should look to regularly empty this prefetch folder to help your slow computer and ongoing pc performance. GO to the windows folder under your lodal hard disk X:\windows\prefetch (X is the drive where you have Windows installed) or %systemroot%\prefetch

6. How many fonts do you really need?
Another tip on how to fix a slow computer is to ensure that you only have the fonts that you are actually going to use loaded. Additional fonts will use memory and computer power – especially TrueType fonts. Get rid of some of these by going to your control panel, visiting the fonts folder and moving the ones you do not require to a temp directory. That way you can bring them back if need be !

Used Computers (Desktops/Laptops)- What To Look For?

Yunan — Fri, 06 Aug 2010 07:11:12 +0000

Nowadays desktops and laptops are much more durable and dependable that they were just five years ago. Therefore, buying a used or refurbished computer is becoming more of a trend.

Suppliers replace their computers on average every 6 months and companies frequently upgrade their equipment. Buying one of these used or refurbished computers can save you a lot of money while still using a quite up to date technology. This is even more relevant if you are not a heavy user (i.e. most of your time on a computer is spent online, you may use a few standard applications once in a while). Even modestly priced computers will more than suffice for these types of demand.

Thinking about buying a used or refurbished desktop or laptop?

Buying a computer is not at all an easy job, one has look get detailed information of the available computers of good and reputed brands. One must take into consideration the size, color, configurations, features etc… While your computer should correspond to your personality and lifestyle, you should always keep in mind the reputation of the brand in the market. Brand counts a lot; you can render good service by the manufacturer if your computer is damaged.

Important handy Tips before buying a computer…

* Verify if the brand is reputed and always buy a good reputed brand. Read about customer service experience for that specific computer issues.

* Check the warranty/guarantee of the computer (seek out computers which still have warranty/guarantee remaining)

* Compare the price of the new model in the market with what price your buying your used computer, try to get the best bargain. i.e. a two year old computer should not be bought for more than half of its original price.

* Check if the computer is outdated (if out of production it is difficult to get spare parts)

* Is the operating system current (Windows Vista/Windows Xp). Earlier versions probably run slower (windows 2000) and would not be advisable unless your needs are limited (i.e. web surfing, Word…). In any event, stay away with computers running on Windows 98 (granted you don’t find many anymore). Also be aware of Windows Vista. Many users are reverting back to XP and that is even more obvious in the corporate world. Why? Vista looks nice but doesn’t bring many technical improvements; therefore IT managers are not willing to implement something new when what they have works just fine. Some domestic users just don’t like the new way of navigation within the Vista Operating System.

* Check if the configuration of the computer you are buying is good.

* Check the speed of the processor. If possible start the computer and see how long it takes to fully turn on. If its slow just turning on, imagine the lack of speed once you start adding software..

Additional Tips for laptops

* Is the battery life good? (search for the computers with a very good battery backup).

* Check for the screen size of the computer your buying and see to it that it is not exceeding the Normal (normally the screen size should be between 15-17). Less than that generally translates in older computers and increases the chance of age failure. Once the screen breaks, you are often better of changing the whole computer.

* Review the connectivity of the computer (Network, USB, Video, Audio…) look to it that it has a good connectivity including wireless.

* Check out the weight. Ensure the computer is light enough for you to carry.

* More details at http://www.bestlaptopsreviews.com/index.php/Used-Notebooks.html

Where to buy used computers:

* Online auctions. Pro: Often offer the best prices. Cons: Cannot validate the accuracy of the described item. No warranty. Tip 1: Some companies will offer warranty for up to two years, the cost is about 12% to 18% of the purchase price. Tip2: Buy from sellers with great feedback, do not hesitate to contact the seller with questions prior to bidding.

* Online marketplaces: Pro: Set prices and quantities – Sometime warranty is available. Cons: Prices can vary a lot, do your homework.

* http://Craiglist.com Contacting sellers on http://Craiglist.com in your local area gives you a chance to meet with the owner and physically test the computer before the purchase

Where to buy refurbished computers:

Refurbished computers can be a great way to buy as they have warranties and are generally sold by manufacturers or companies affiliated with them.

* Manufacturers websites will tell you how to buy directly from them or from their authorized sellers. Pros: Warranty, established companies. Cons: Prices are higher than regular auctions (you pay more for peace of mind)

Buying a used or refurbished computer can be a great way to save money. If you use some of the advice discussed above you can avoid many pitfalls. One last thing concerning laptops, make sure you have a good bag to protect your computer from a fatal accident. Your bag should be big enough for a 17 inch screen computer as it is rapidly becoming the norm, you will probably change your computer within a few years, the bag you may keep a lot longer.

Good Buy!

10 Benefits of a Computer Enclosure Over an Industrial Computer

Yunan — Sun, 01 Aug 2010 07:12:54 +0000

Demands are high for computing in industry. Industrial machines have to cope with many hostile elements whilst also providing reliable computing. Traditionally industrial computers have been specific, bespoke machines. These industrial computers tend to run old hardware and versions of software. Whilst this has the advantage of making the machines stable and reliable, the out-dated technology may mean the processes controlled by the machine are not done as efficiently.

These machines are also very expensive, not just to buy but also the maintenance. Industrial computers have to be maintained by service engineer, often forcing shutdown of production lines they also have to be replaced periodically as the hardware and software will eventually become obsolete. All computers eventually fail but an industrial computer enclosure means that over three generations of computers can use the same enclosure.

Industrial PC enclosures are a more efficient, affordable and reliable alternative to these expensive machines. The main benefits of an industrial computer enclosure are:

1. Withstand the same environments as an industrial computer, whether that is dust (including explosive atmospheres), dirt, grime, oil, grease and water (even completely doused). Enclosures are rated using European IP ratings that give a clear indication to the types of environments the enclosure can operate in, for example IP 65 totally protects dust whilst protecting against strong jets of water, (the first digit, 6, represents the dust protection the second digit, 5, the water) while IP 66 offers the same dust protection but the enclosure can be completely immersed in water.

2. Enclosures can also withstand the same shocks, vibrations and tampering as the enclosure can be built from robust materials and the enclosed PC can be fitted snugly and secured with shock absorbing bolts. Enclosures can also be securely locked and bolted to floors or walls to protect against theft.

3. For computing in extreme temperatures, computer enclosures can in fact work to a better standard than industrial machines as the extra cooling and heating units can be replaced if they are not working as efficiently as they should (a sealed industrial computer that is running too hot or cold would need to be replaced or returned for an upgrade).

4. Computer enclosures can enable a PC to run equally as reliable as an industrial computer as the desktop PC housed in the enclosure can be any conventional machine, from a trusted office workhorse to the latest all singing, all dancing off-the shelf PC.

5. A computer housed in an enclosure is also far cheaper than an industrial computer. Apart from the initial outlay for the expensive bespoke industrial computer, enclosures can out live an industrial machine by over a decade as an industrial computer will eventually have an internal failure (as all computers do) or become completely obsolete and will need replacing. However, an enclosure can be reused to house another machine and will in general house three generations of machines.

6. A computer enclosure can house monitors, printers, touch-screens and all manner of computing equipment (including the peripherals such as mouse and keyboard ) or they can be combined with water/dust proof sealed keyboards and mouse.

7. As an enclosure houses a conventional PC, any repairs or upgrades can be carried out in-house in minutes rather than have to wait for an engineer and have to shutdown the production.

8. Enclosures can be manufactured from a range of material including food grade stainless steel.

9. Enclosures can be lockable and secured to walls or floors to prevent theft or tampering.

10. Enclosures allow you to choose which software or hardware to run inside the enclosure rather than suffer out-dated technology.

With the demands of industrial computing so variable and extreme, industrial PC enclosures offer a flexibility that even conventional industrial computers fail to match whilst also offering the same protection and reliability for a fraction of the cost. PC enclosures are ideal for even the most hostile industrial environment and while specialist PCs will always be required for certain tasks the majority of uses for an industrial computer can be achieved using a conventional PC housed in an industrial computer enclosure .

Almost everyone owns a computer and some are not aware on how to maintain their computer in good shape. If the computer slows down there initial reaction is that the computer is infected with a virus. Though, this is true but not all the time it is the main cause of the problem. It may be as simple as there are programs that are running in the back ground that should not be and many more.

Speed up computer by searching for the main cause of the problem and treating it. Here are the main reasons why the computer slows down and how to deal with it:

1. There are sectors on the hard disk that is not used, which makes storing new files difficult. This will relatively slow down the computer because it will have a hard time looking for a good sector to store information. There might be an available sector but it is not enough so it will look for another available sector and so on.

To speed up computer, defrag the computer once in a while. Twice a month is ideal and you do not have to be in front of the computer all through out when doing this. All you need to do is start the Disk Defragment tool and choose the drive you want to defrag. Once it has started running then you can just leave it because it will take several hours to finish.

2. Corrupted files can cause the computer to slow down. It can also result to the computer crashing which makes it difficult for the computer to shut down. To speed up computer, use the Scan Disk tool included in Windows operating systems. This will search for files that are not being used in the computer and that are safe to delete.

The files include temporary Internet files, Cache, Cookies and files in the Recycle bin. You have the option to delete the selected files or not.

3. The most common cause of a slow PC as mentioned earlier is virus infection. The computer can be infected after browsing a malicious website like pornography sites. Adware or spyware can be installed in the computer where in it can display several advertisements on the computer. This will gradually slow down the loading of programs and makes it impossible to work continuously.

Speed up computer by installing a reliable antivirus program. It is recommended that antivirus programs must be installed before using the computer especially when it is a brand new computer.

4. Sometimes unnecessary programs are installed in the computer that is not used frequently. Like for instance games, programs that you have forgotten to remove after trying it or trial programs.

Open the Control Panel and open Add/Remove Programs feature. This will display all the programs that are installed in the computer. Browse the list and look for the programs that you are not using then remove it. After removing programs always make it a point to restart the computer for the changes to take effect. Also if possible, look for the folder associated with the program under Program Files and delete the folders.

5. Programs that are running in start up can also slow down the computer. If a program automatically starts in Windows reboot it will access the memory and this can take up a space. And if several programs are running in start up all at once, the programs will compete on accessing the memory. This will make it harder for the computer to start completely.

To speed up computer start up, do not check the option that says “Automatically start on Windows Reboot”. This option is usually seen under the Settings of the program.

Registry cleaners are also important tools that you should have installed in the computer. This will help you maintain the registry and computer performance in good shape.
