My fan get's loud and the computer slows down with the more time I spend on it, per session. Ca

I have a Dell desktop. It starts up very quiet and fast. It gets louder and slower as time passes and I use it. Sometimes with just internet explorer open, it has 100% CPU usage as quoted by the task manager.

So I started with running a defrag and disk cleaner. Nothing changed.

Then I uninstalled programs I never used, to free up space. I have about 60% free space now. Nothing changed.

I ran msconfig and edited it to not start up useless programs, and not to run useless services. Little changed, but it took longer to show problems.

I ran a program to free up RAM. It made my fan louder and computer slower when I ran it.

I have checked for spyware with 2 different utilities and visuses with a another different 2 utilities. Nothing changed!!!

Any other ideas? It doesn't start this way, any ideas?

If you fan is making that much noise, it's probably going bad and your CPU is overheating, causing your computer to go way slower. Get a replacement fan and install it, or send it to Dell (if it's still under warranty). Or, you can send it to me and I will replace it for you, I am a Dell Certified Technician :-)
