This is getting annoying. I'll be in the middle of a game, whether it's battlefield 3 or minecraft, and randomly my screens will flash, then go dark. I hear a post beep, and it restarts, but amazingly slow (30mins to desktop). At no point do my case LEDs switch off, so its not losing connection to the power supply. Also, this was happening before my recent overclock, so that's ruled out. This doesn't only happen during games, but usually that does it. I've noticed Alt+Tab and Alt+Enter are touchy with this too. The screen crash makes me think it's a graphics issue, and I hope it is thay because I'll be upgrading in a week or so. Thanks in advance.
