The problem that i have is that everytime that i play World of Warcraft, the computer reboots itself after a certian time. WOW is the only game that i have installed. The computer may be on for days without playing any game and it runs fine, but 45 minutes to 90 minutes into WOW, it reboots with no BSOD or error message.
Here is the original hardware that i had:
MB: Gigabyte DQ6
RAM: HyperX 6400 2 gigs
CPU: E6400 with stock cooler
VIDEO: X1900XT 512MB (MADE BY ATI)
Sound: Soundblaster Audigy Platinum with front I/O
Power: Antect True Power 2.0 480W
HDD: Seagate 7200.10 320G
OS: Winxp SP2
So the first thing that i changed was the power supply. I went back to the store and they exchanged it without any questions. After 1 day it started again. So i changed the MB to an ASUS P5B, but the problem still occured. I went back and bought new RAM OCZ reaper 2 gig kit, installed that, but the system still reboots. The only things left to change are the CPU, VIDEO or Sound. Every time that i have changed a part, i have reinstalled the OS. THe motherboard is well mounted and there are no shorts on it. I have applied a generous amount of CPU thermal compound on the cpu and it doesn't overheat. Idle is 20 degrees Celcius. Can anyone suggest anything at all?
Sound is easy to check, just pop out the card. disable it in the registry and play. There is a slight chance it the sound card, but the only time I've had one go bad on me is after a cascade failure took out all the other components.
Have you run any stress testing (like prime 95) to heat up the cpu, but not necessarily the video card?
And a quick check to make sure the fans on the video card are spinning wouldn't hurt. The cards can idle fine with a broken fan but once stressed if those things aren't working goodnight.
