Hi guys, I've been having some pretty bad trouble with my desktop PC recently; it started about six days when I came home to find it had shut itself off but still had power. Resetting soon showed that my computer could make it as far as the desktop and last for maybe three minutes before crashing (lose sound, video and as far I could tell everything else except for power). It kept power and the fan for my video card would get extremely loud. I've since made this problem much less extreme by uninstalling my video drivers and installing up to date drivers in safe mode. The problem is that it still does it but only when I'm doing something fairly intensive like certain video games or playing high resolution videos in media player classic (other media players don't seem to set it off). I can usually play a game for about three to five minutes before it crashes. The video card fan does still get louder when this happens but not as much as it did before. I've run memtest and found no problems with my RAM and I tried using driver sweeper to more thoroughly remove my video drivers but that has had no effect either. Specs: Windows 7 Professional 64 bit OCZ Vertex 128GB Solid state Seagate Barracuda 2TB HDD Processor: Intel(R) Core(TM) i5 PSU: Antec 520 (about 6 months old) Videocard: Geforce GTX 550 Ti (about 18 months old) Motherboard: Asus P7H55-M RAM: 4096MB Corsair Vengance I've been looking for a solution for almost a week and I'm on the verge of either wiping my solid state and doing a fresh install of windows or getting a new video card. Any advice would be much appreciated.
