Their are a few things that can cause a computer to run slow: dust, poor ventilation, insufficient hardware, damaged hardware, registry errors, disk fragmentation, malware, too many start-up programs, too many running tasks, firewalls, anti-malware shields, insufficient disk space, and junk files.

Warning:

--Anti-Virus Shields, Anti-Spyware Shields and Firewalls can and usually slow down your system, but are important to have.

--When you clean your registry you can damage your system.

A cool program I like to run before performing system slowing tasks - SmartClose

This program closes out of most unnecessary running tasks and programs, you can add tasks you want to keep running to a list. Programs can be restored upon request or at the next computer boot.



Uninstall unused programs, update your computer regularly, update obsolete or old programs.

Run Disk Defragmenter - Start> All Programs> Accessories> System Tools> Disk Deframenter



Remove Programs from Startup - Start> Run> msconfig

--Click on the Startup tab and uncheck the boxes of programs unnecessary to run at startup



Install and Run ONE Antivirus Program (Can cause system to slow down if the shield is active)

--AVG Anti-Virus Free Edition http://www.grisoft.com/

*--Avast Anti-Virus Home Edition http://www.avast.com/

--Avira Anti-Virus http://www.free-av.com/



Install and Run Anti-Spyware (Can cause system to slow down if the shield is active)

To Maintain Your Systems Safety a Firewall is Recommended (Can cause system to slow down if the shield is active)

If all this fails then you need new hardware/upgrades or you need to format/reinstall your hard drive/operating system.
