Ok, I just recently started getting the blue screen of death and at first I thought it was because of a virus, so I scanned my laptop with the best software I could find and found about three trojans and went through the whole process to get rid of them. I thought the problem was over, but I was wrong

I looked for every possible solution and couldn't find any...

I'm really hoping that someone can help me figure this out, so please respond...
Here's some info about the problem:
It's running on windows 7 ultimate (I know this is a vista forum, but I'm desperate)

It usually happens when I wake it up from sleeping or when it gets a bit hot (I have to keep a fan under it just about all the time now) and this wasn't a problem before... One time I also got a small blackout and a notification at the bottom right corner said something about "NVIDIA has stopped working but recovered" I feel that this things are all inter-related. Anyway, please help out.
Thanks,
