I've been having graphic corruptions, black screens and reboots for over 2 weeks now. These problems occur after ~40 seconds of gameplay in any 3D game. When not playing a game, the machine is 100% stable. Only a day before the problems started, everything used to work ok, and afaik I didn't change anything.
When I underclocked my graphics card, the problems would occur only after 20+ minutes. This led me to think that it was a problem with my graphics card. I replaced my card with another one, and the problems persisted.
Because this only occurs after displaying intensive 3D graphics for some (short) time, this led me to think that this is a hardware problem, with two likely causes:
- The A8N-E motherboard (where the built-in sound card already had a damaged output channel for a couple of months)
- The power supply unit (unlikely, should be of good quality with 2 temp. controlled fans)
Can anyone else shed some light on this? Is there anything else I can test, or perhaps another possible cause? I'd like to have a good diagnosis before I return any component back to the manufacturer. Thanks in advance!
