So this past week my computer was slow thought I had too much on it starting del old stuff (larger music files).

Then also the fan (maybe I dont know) kept coming on way too often. So I got a can of spray and blew all sorts of areas out. It doesnt keep coming on anymore.

You would think that would be enough.. I was sitting in bed then looked at my pc (desktop) and there were 8 million things open on it (pop ups/spyware/something)

I downloaded Ad Aware - now from what I can tell and read I also have VirusRemoved2008 - it keeps popping up something about my pc. I later read it is spyware. I scanned several times, shut my pc down to 'refresh' if you will and now..

MY COMPUTER WONT STAY ON - EVERYTIME I TURN IT ON IT GETS THE TO THE DESKTOP I SEE ICONS AND THEN IT REBOOTS AND JUST WONT STOP.

I did manage to boot in safe mode - THAT DOESNT HELP ME SINCE I DONT KNOW WHAT TO DO.

I have no idea if it is my fan gone bad, or power supply or the virus. Where do I start?

Thanks!
