Hi I am really stumped on this one. Whenever I play a high graphics game on my computer, after some time, it just shuts off. All of the fans stop and all that works is an LED light in the front. This started happenening a little while ago and I thought it was my video card so I bought a new one. I replaced my old FX5200 with a Radeon 9600. However, while the problem occurs much less often, I am still having these random shutoffs during games. This happens ONLY in games, because I can leave my computer on for many hours without it crashing until I play a game. Another thing is that I cannot turn my computer on for about 30 seconds after these shutoffs. I suspect its either my power supply or processor, as it is unlikely that the ram or hard drive are causing this. I am going to run a program called memtest and another called hotcpu tester to test these out tonight but I don't think that this will help. Does anyone know why this could be happening. Just to clear this up, I have all the newest drivers for my video card, mother board, etc. I also checked the temperature of my CPU and my Video Card, which is staying at about 110 and 90 degrees Fahrenheir, respectively. I really have no idea what to do, so any help would be greatly appreciated.
