I recently built a new computer with:
Antec 900 case
2x2GB G-Skill RAM
Intel Core2 Quad 2.66 (Q9400)
Gigabyte GA-EP45-UD3P Motherboard Rev. 1.6
EVGA Nvidia GeForce 9800 GTX+
Corsair 650W Power Supply
running Windows 7 64-bit.
Now on to the problem: At seemingly random intervals (sometimes every 30 minutes, sometimes every 2 hours or so), my screen/computer just fails, and I have to reboot. The screen either:
-Freezes with my windows/desktop still there, can't move my mouse or type, and there is a buzzing noise coming from my speakers.
-Goes black, and there is a buzzing noise
-Displays this, no buzzing:
-Displays something like this, no buzzing:
I've yet to overclock, run any games, or anything like that: I'm just listening to music, chatting, and browsing the web. My core temps are all under 45C and my GPU is under 40C. Also, when the screen locks up, I lose connection to my iTunes stream to my laptop and can't connect via TeamViewer, so this may be more than a graphics problem....
My BIOS is version FB for the Gigabyte mobo, but the latest version FD doesn't really address anything i would think is associated with my problem, so I've yet to update that. (Description of the BIOS versions from Gigabyte) http://www.gigabyte.com.tw/Support/M...ProductID=3137
Does anybody know what might be the cause of the problem and any possible solutions to try?
