P8p67 Deluxe black screen, crash, VGA LED

[b4t0s4i]

I seem to be having some problems... Started out that my screen would go black, and my fan(s) (couldn't tell if CPU or GPU) would go FULL speed. Temporary remedy was reboot until it happened again. Cleared CMOS, checked caps, ran everything stock speeds, reapplied thermal paste to CPU, still happened. Upped the voltage on my cpu and it seemed to help. Happened less often and only when gaming hard. All temperatures are fine.

The problem I'm having now, is that my screen goes black, sound hangs then cuts off, and system restarts itself, fails to post and VGA LED comes on. Only happens while gaming. However, gpu benchmarking and stress tests do NOT cause this failure. Thought maybe I'd have to up the voltages on the GPU but I wasn't sure. Again, all temps are fine.

My computer specs are listed below.

Can get screenys/pics of voltages, etc. if requested and needed.

Can anybody help?

Definitely a hardware problem; Either some components are not properly seated in their sockets or one of your components is faulty;

I see that you've tried the GPU stress testing. How about CPU burn-in and RAM testing? Prime95 is quite good for CPU and some RAM (not dedicated, but part of the CPU testing) testing - try to run all available tests there and execute them for some significant time span (for example - like 2hrs - as if you were playing games or doing anything comparatively demanding). Better, yet - since you have such a modern high-end system - run the GPU testing (FurMark?) + Prime95 together and see what that does. I'd say that this should fairly quickly expose the problem;

Order of plausible problem sources:
1. GPU/CPU
2. RAM
3. PSU
4. Motherboard

EDIT: the test was MSI Kombustor when it reached the "combined test" that looks all vintagey. Can't test it in another system any time soon. Might just RMA it but not sure it'll fix it. I'm sure 850W is enough power... Also burn-in test was fine, turned all fans to auto and let it run, temps went higher than ever before and nothing happened, so temps are apparently not the issue. Card is seated properly and all "pins" on card / board are fine.

So the first suspect is the video card then. Do you have the possibility to check it out in another system?

Heaven benchmark ran fine, no problems at all.
OC scanner crashes sytem after ~40 minutes. No artifacts reported before crash.
Considering SLI with another 570... BF3 drops to ~30 fps at some points, can't have that now can we?
Put in for RMA with EVGA.

Read edit above for answer to last question.
