It's prabally caused by the new commen virus, Don't remember what it's called....But I just recently had it, and I'm pretty sure I got it from my friend's burnt CD. I was having some other odd problem's myself when I got it so i reformated my PC to see what It would fix to make sure my other problem's weren;t virus called also since i was stumped on hardware and din;t want to replace peieces one by one till it worked.
The Blue screen Stop thing went away on my PC, and that's about it, my other problem;s still exist which is what i expected but It was worhth a try. To get rid of it you can "Prabalaly" Just run a few virus scan's but if you have to reformat, I only did that because of opther problems, but you shouldn't have too.
