Why computers slow in speed

Computers can sometimes slow down over time. Some computers operating slowly since the first day. This is usually happens in third party computers. (Not in branded computers) Third party computers assembled collecting hardware, and there may be incompatible hardware parts with each other. When assembling computers people do not concern about the specification of each part. But it is very important to get maximum advantage from a computer. If you assemble a computer with incompatible parts those devices do not operates with their best performance. To work computer in it's maximum speed, all the hardware parts should work in their maximum efficiency. So if your computer operates slowly than expected since the beginning, check your hardware configuration again.


There are a number of ways and issues that slow down a computer speed after working properly for some time. Those issues can be fixed by getting knowledge about following areas.

Check for viruses

The most effective reason for slow down is virus attack. Viruses are special programs written to run with windows invisibly and to interrupt the normal computer process. So the virus not only interrupts the process, but also take some space from the memory to run itself. There are different kinds of viruses in the operation today. Spyware, Trojans, Adware, Malware, etc are always slowdown the computer speed, even some of them are not harm your computer.

To get rid from those you need a good virus guard to be installed on your computer. Several virus guards been introduced today by various institutions. Some of them are free and some are charge by annually. But the important thing is virus guards may too slowdown your computer speed. So you may think it's better to have malwares or trojans in your computer than a virus guard as both of them slow down the speed. But There are several virus guards which does not effects the computer. They run in the background them self without slowing speed and protects your pc from virus attacks.

Kaspersky virus guard (all versions) is currently working well. It will not effect the computer speed. But there are several configurations you must do. If you do so you can be protected from viruses.

It is not enough you install a virus guard and waiting to be protected. You must update it regularly. If you have internet connection to your computer normally virus guards updated automatically. If not, you must update it manually. There are several methods to update virus guards.

Remove Temporary Files

Windows XP installed machines usually creates temporary files while operating the computer. There are several methods included in windows to remove those unnecessary files from the computer. But most PC users do not care about clearing up those unwanted files from the computer.

To clean temporary files from your computer :
Open My Computer ==> R click on drive C: ==> Properties ==> Disk clean up ==> Check unwanted files ==> OK

Check for unnecessary programs which were automatically installed and running in background

Most PC users do not realize that their computers are probably running a number of unnecessary programs in the background that tie up system resources and slow down the system. Sometimes these programs display an icon in the system tray. These programs starts automatically with windows and running in the background without making changes in the desktop. Those programs will use system memory to run and reduces the memory power to be used for usual applications. They can be prevent from starting with windows by deleting the desired file in startup folder in start menu. (Start ---> All programs ---> Start up). These kind of programs usually installed automatically from internet.

Do not copy your data (Songs, videos & other essential files) into primary partition. (Normally Drive C:)

If your windows operating system installed in drive C:, do not fill it up with your data. Low drive C: space will probably slow down the speed of your computer. Do not copy your data into desktop or My Documents too, as the desktop / My Documents also belongs to drive C:. A general rule of thumb is to maintain at least a gigabyte or two of free space on the primary hard drive. If you already have your data in drive C:, move them to any other partition of your hard disk.

Defragment your hard drive

When working on computer for a some time the hard disk become very fragmented. That is, the data on the drive is scattered all over, rather than being organized into discrete areas. This causes the PC to slow down because it has to search so much for any data. The Windows defragmenter (usually found under the Start Menu/Programs/Accessories/System Tools) comes with Windows and is an adequate diagnostic tool. Remember to run the defragmenter over night, since it usually takes a few hours to finish the process.
