I've owned my XPS 700 (running XP) for I think two years now, and lately I crash randomly when I'm in a game. What happens is my screen goes blank (monitor even pops up the no signal square in the middle) and my computer fans start going really hard and everything just locks up. If I had audio, it's looping. When I try to boot up after the crash, there's a high chance my screen won't come back. For some reason when it doesn't come back, my computer turns off very quickly as opposed to having to hold the button for 5+ seconds. I've talked to a friend about this and he suspects a problem with my video cards or motherboard. I updated my drivers and I still have the same problem. Any help is appreciated.
