It could be a virus/worm thing.

Cause I had one that was eating up 50% of my RAM (I have 4 gigs)

Can you open Windows Task Manager and see what's eating up CPU? Because if it is what happened to me, there will be something with a name extremely close to something that should be running but eating CPU. End that process if that's happening.

Then if IE works then, use this http://www.microsoft.com/security/sc...s/default.aspx

It is free, will catch and get rid of worms (if you do a full scan) and it's good for 10 days before you have to re-download (due to updates and everything)

It's the best thing if it isn't like a file being corrupted. And Norton is horrible from my experience-kills computer speed even when not running a scan. I suggest AVG which comes in a free edition. But that's just me.
