Hi,
I'm trying to diagnose a problem with my graphics card (I think). My specs are:
Power supply: Antec Neo Eco 620C
Mobo: ASRock Z77 Pro-4 M
Ram: 2x4GB Gskill
GPU: Gigabyte Radeon HD 6850, drivers 12.8.
CPU: Intel i3 2120
OS: Windows 7 64 Bit Ultimate
What I get is basically completely random crashes (the computer can run for days before anything happens or sometimes only 10 minutes before it crashes). They differ - sometimes BSODs (they usually say 'Hardware Malfunction', sometimes crashes with restart, screen freezes, but more commonly it is either a grey/black screen with horizontal fragmenting. In cases where it freezes or gives strange lines, I will often get a loud buzzing sound (from my speakers/headset).
It is not temp, everything is running at <40 degrees.
This guy seems to have a very similar problem, also using 6850s. http://www.tomshardware.com/forum/356148-33-radeon-6850-crashes-freezes-random
I've run memtest for about 6 hours with no detected errors.
This has been happening for a while now, and I could really do with getting it fixed. Anyone have any ideas?
