This has been irritating me for the past 4 months or so. Basically, if I play a game like WoW, Left 4 dead, or HAWX at maximum graphics settings the computer will freeze. Sometimes within minutes, sometimes after an hour. In Left4dead, the freeze occurs 75% of the time while loading a new level. The game freezes, and seconds to minutes later the cursor will freeze to. However, if I am playing music in the background, that will continue to play. The PC is completely unresponsive once the cursor is frozen (can't soft shutdown, cant use keyboard or mouse to stop the music, etc). I have tried every graphics driver going back a year but it didn't fix the problem. I even tried removing the TV tuner card to see if that was it, but nope, still freezes. I have replaced the video card twice, this time with a cross shipment so I got a completely new one, and I've RMA'd the motherboard once. The BIOS is the latest. The firmware on my hard drive and BIOS on the video card are the latest. All of my drivers (network, chipset, sata, tv tuner, audio, video, webcam, etc) are up to date. My specs:
Vista x64 SP1 Ultimate
Seagate SATAII 7200RPM 500GB 32MB Cache HDD
8GB (4x2GB) A-Data 800MHZ RAM
Corsair 550watt 80plus PSU
Diamond Multimedia ATI Radeon 3870x2 GPU
Gigabyte P35-DS3L Mobo
Intel Q6600 2.4GHz CPU
Any ideas?? I've also tried disabling all my startup programs but that didn't help either. Since I've replaced the video card and motherboard... I have no idea what else to try... maybe replacing the power supply? I can run Prime95 and Memtest+ for days with no hitches, and all of the temperatures inside my PC are normal.
