Sunday, January 17, 2010


This issue can be caused by any of the below possibilities.

1. Hard disk drive is short on available disk space.
2. Several software programs have been installed/uninstalled leaving behind bad files and/or confusing the software.
3. Data Corruption.
4. Missing Windows updates / Outdated drivers.
5. Computer is overheating.
6. Corrupt OS.
7. Bad Hardware.


Below are steps for Microsoft Windows users that should help speed up the computer or determine why the computer is running slow.

Not enough hard disk drive space

Verify that there is at least 200-500MB of free hard disk drive space. This available space allows the computer to have room for the swap file to increase in size as well as room for temporary files.

Hard drive corrupted or fragmented

Run Scandisk or something equivalent to help ensure that there is nothing physically wrong with the computer hard disk drive.

Run Defrag to help ensure that data is arranged in the best possible order.

Background programs

Remove or disable any TSRs or programs that automatically start each time the computer boots. See document CHTSR for additional information. If you're wanting to see what programs are running in the background, how much memory they're using, and their CPU usage open Task Manager. Also, if you are running Windows 7, you can run Resmon to find out which programs are taking up a lot of space.

If you've got an anti-virus scanner on the computer, spyware protection program, or other security utility make sure it's not running in the background as you're trying to work. Often when these programs begin to scan the computer it can decrease the overall performance of your computer.

Hardware conflicts

Verify that the Device Manager has no conflicts. If any exist resolve these issues as they could be the cause of your problem.

Update Windows

Make sure you have all the latest Windows updates installed in the computer. A

Update your drivers

Make sure you've got the latest drivers for your computer. Especially the latest video drivers. Having out-of-date drivers can cause an assortment of issues.

Computer or processor is overheating

Make sure your computer and processor is not overheating, excessive heat can cause a significant decrease in computer performance some processors will even lower the speed of the processor automatically to help compensate for the heat related issues.

Memory upgrade

If you've had your computer for more than one year it's likely you're computer is not meeting the memory requirements for today. We suggest at a minimum the computer have 1GB of memory.

Erase computer and start over

Finally, if none of the above solutions resolve your issues, it is recommended that you either reinstall Windows and/or erase everything and then start over.

Hardware issues

If your computer continues to be slow after going over each of the above recommendations it's possible that your computer is experiencing a more serious hardware related issue such as a failing component in the computer. This could be a failing or bad CPU, RAM, Motherboard, or other component.

you can also use some free registry defrag tools to build a compact and linear registry from the old, thus speed up responsiveness of applications, and improve the overall performance of Windows
