Computer freezes, screen goes black when both the CPU and GPU are under heavy load.
It usually happens when playing Guild wars 2, during big boss battles with TONS of other players around (even with all settings on min)... doing anything else in game, playing anything else is also fine. Since GW2 is CPU and GPU heavy, I decided to stress both out via Prime95 and Furmark.
I'm able to recreate the freeze when running both stress tests simultaneously (though even this seems to work out just fine many times, but if I stop and restart these tests repeatedly a couple times, it'll recreate the freeze/black screen).
I solo stressed just the CPU multiple times, and it was fine. Did the same for the GPU, no problems. Ran a memtest overnight, no errors. Temps are great, CPU doesn't go over 34C, vid card maxes out at about 67C. Just seems to happen when both components are under load at the same time.
The PSU is a year old, and has been working great since I got it. Does it seem like maybe it's going bad? I always assumed if it was a PSU issue the PC would just shutdown instead of freezing. Anyone have suggestions on what else it could be?

I'll probably try to pick up a PSU one of these days and hope that was the cause (still have 4+ years left on the warranty).
