Slow Computer but I have tried everything

[ross]

Hey Guys/Girls

My computer is running super slow all of the sudden.  I got an internet security system from staples (by Panda software).  It found a ton of syware and 3 trojan virus.  It clean them up.  I also got "error Nuker" and that found 251 error, as well as I am running PC doctor.  At this ponit everything says that my system is good but it still is so slow it is crazy.  I have plenty of memory as well as hard drive space.  What could be the problem?

How much stuff have you running in the background? Hit [Ctrl] + [Alt] + [Delete] and see what's running - at a bare minimum you should have "explorer.exe" and "systray.exe" running for Windows to function, and you'll probably have your AV app and firewall up there too. You won't need much more than that.

In the "Task" tab or "Processor" tab?

Nuke Error sounds dodgy..

Format and reinstall Windows to start with a fresh lane.

How do I do that?

Have you tried defragging your computer? I suggest buying Diskeeper, the best defrag tool ever. Formatting your computer is usually a last resort. You will lose all your data.

Go to Start > Run > msconfig
Go to startup tab and untick things you don't use.
