Interesting Problem

[vlad321]

So this problem is unlike any I've dealt with before, given what I've tried doing to fix it. Basically in a nutshell, I'm playing my game and all of the sudden it goes from 60+ FPS down to no more than 10 and it stays like that for a while then it goes back to normal 60 FPS. This is happening in every game all the way back to Warcraft 3 and affecting everything up to and including Dead Space. The most interesting part is that when it happens and I'm playing a windowed game it is usually accompanied by a flash on my screen, either right after or right before the slow down. Then sometimes it flashes a few more times or not at all before it gets back to normal. I've never had a video card hardware problem so far and I'm wondering if that's a possibility at all.

I also reformatted my computer a month ago and everythign is up to date and the only things I have gotten off the internet are Stea, EADM, and the games I got from there. Anyone have an idea on what's screw this up?
