Occasionally, a program on my computer will crash, and take everything else down with it. Any attempts to open or reopen programs will result in a loud static sound and a graphical error where it looks like the screen is jagged and being torn apart, followed by another crash. I've searched everywhere, but can't seem to find a solution to the problem, or even know what's causing it! The issue occurs frequently when playing Diablo 3 Beta, occasionally when playing Starcraft 2, and now it's started rarely crashing in Mass Effect 3. Can someone please tell me what could be causing this and how to fix it?
Edit: System Info:
Motherboard: Asus M4A87TD/USB3
Graphics Card: Nvidia GeForce GTX 460 SE
Processor: AMD Phenom II X4 970 Processor 4.0.1 GHz
Ram: 8 GB
OS: Windows 7 Ultimate 64 bit
Let me know if any additional info is needed. Those are the things that come to mind off the top of my head.
Checking drivers was the first thing I did, but this has been a problem for a while now, and updating drivers/games doesn't seem to have an impact. Given that the games seem to simply trigger the crashes that then spread to everything else, I don't think it's the games either.
