Why Is My Computer So Slow?

There could be many reasons for your computer to slow down. If you have background programs running in your computer it takes up memory space making your computer run slow. The programs running at the background take up substantial RAM space leaving little room for any task execution. You will find quite a few icons in your system tray. These are some of the programs that are running at the background which not only take up memory but also CPU usage. At the time you boot your computer, some programs start by themselves. To have your computer run normally, you need to remove these programs selectively from your ""program start up". To configure your start up programs or to delete the unwanted ones, you should use Start/Search function in your Windows system.

The computer uses the free space in your hard drive while executing instructions. If you do not have enough free space in your hard disk, your computer will tend to run slow. As an estimate, you should have at least 3 to 4 MB of free space available in your disk for the computer to run normally. If you have more than one drive, you must make sure that you have free space left on your "C" drive, or any other drive where you have Windows operating system installed. If you find you do not have enough free space, you should try and delete or remove some of the programs from that particular disk.

At times, the updates of your Windows operating system or any other software may run automatically when you are browsing the Internet. This mostly happens at the background, rendering your computer to run slow for as long as the update is not completely downloaded. As soon as the computer finishes downloading, your computer should come back to normal speed. In order to avoid this, you would need to disable automatic updating.

Your Windows operating system scans your hard drive to retrieve required data at the time it is executing assigned tasks. If data in your hard drive is fragmented, Windows takes longer to scan the hard disk in order to find that data. This makes your computer run slow. You need to regularly de-fragment your hard drive, so the data remains contiguous. By de-fragmenting the data in your hard drive, your Windows operating system takes less time to scan the hard drive to retrieve the required data.

Games software requires larger RAM to run smoothly. If you find your games in the PC are running slow, you should upgrade your RAM to the extent as required by your games software to run normally.

If you have two drivers of the same device installed in your computer your PC may become slow. For instance, if you have two video drivers in your PC it will be conflicting with your Windows operating system. The system will not be able to decide which driver to use in order to drive your video system, resulting in slowing down your computer. To put computer back in its normal operation, you need to remove one of the video drivers from your system. If you want to know which component in your hardware system is conflicting with Windows, open your control panel and then click on the "system". Click on the "hardware" tab to view the device manager. There you will find all your conflicting hardware components marked in yellow, and you would either need to re-load the drivers for these devices or remove them if you find them of no use.

As you are browsing the Internet, there are possibilities of viruses and spyware creeping into your system. Opening unknown attachments could also make your computer vulnerable. Virus and spyware will make your computer run slow. You must have the right ant-virus and anti-spyware software installed in your computer which can detect and remove known viruses and spyware programs. Spyware is malicious software which runs at the background, making your computer run slow. It is also responsible in passing personal information to the hacker when you are connected to the Internet.

Computers tend to get slow as the Windows registry becomes larger and larger. As you use your computer, installing and uninstalling software, executing tasks, etc., the registry of your computer develops errors. With your Windows operating system constantly looking for relevant data in the registry system, the errors cause conflicts. Also, Windows takes a longer time to find the required data from the registry as the registry starts to get larger, making windows take more time to scan the system. In this case your registry needs to be optimized by removing the errors in the system. You must use an appropriate registry cleaning software to put back your computer in shape.
