Hello, I have just built a new computer and every once in a while when im playing games (COD4, WoW, Warcraft 3) My screen will lock up and then I will here a puttering noise from my headphones for about 4 seconds then nothing. I then have to hard boot my computer. Ive done a mem test for over 12 hours with no problems, CPU runs hotest at 55C, GPU about 70. Only thing i could think of was the GPU overheating but then I froze once when i was just installing a program. I also thought it might be my old IDE HD but then i took it out and installed windows on my SATA and it is still doing the same thing. My specs are: AMD x2 +6400 XFX Geforce 8600GTS XXX Thermal Take V1 HSF MSI K9N SLI Platinum nForce 570 SLI Athlon 64/Athlon FX SktAM2 DDR2 ATX Motherboard w/Audio, Dual Gigabit LAN, RAID/Serial ATA Retail ASUS DRW-2014L1T 20X SATA DVD Burner Black Corsair TWIN2X2048-6400 2GB Kit DDR2-800 XMS2-6400 Xtreme Performance COOLER MASTER RP-650-PCAR eXtreme Power 650W Power Supply Retail
Well, your power supply seems to have enough wattage for your system so power doesnt seem like a problem. Do you have the latest nvidia drivers?
