Hello, as you can guess from the title, I've been having trouble with my computer shutting off mid game. Well let me describe that in more detail, after 20-30 mins of playing a high end game (such as Crysis, Deus Ex, Assassins Creed, ect.) my screen stops displaying images like I unplugged the video cable and my computer locks up. All of my fans are still spinning I just can't access anything at all. My pc specs are:
CPU: AMD Phenom II X4 955
GPU: ATI Radeon 5830
Mother Board: ASUS M4A78
Power Supply: Rosewill 500w
RAM: 5GB DDR2 (2x2GB, 1x1GB)
I also have a mid tower Rosewill case with four 120mm fans and one 140mm fan. I've tried a ton of different things to solve the issue, but to no avail. First i tried cleaning out the system with canned air. After that, I used the program speed fan to monitor the temp of my PC to check overheating issues. My graphics card got up too 65-70 degrees Celsius before the screen went black. To cut down on the temp, I manually raised the fan speed on my graphics card to around 90% and lowered the memory clock to about 900 MHz (down from 1200 MHz). This brought the temp to around 50-55 degrees Celsius under load, and still would black screen. I've tried replacing the graphics card with a known good one and the issue still remained.
When I check event viewer for an error code, it only shows the unexpected shutdown code, and the unclean shut down code, and that's it. I can't think of anything else other then trying a new power supply, but I don't have one around and I'm not sure that is the issue. Does anyone have an suggestions to help me out?
