My PC restarts while under load. It completly shuts down for a few seconds and boots back up. I've started getting this problem around a week ago, when I first played BF4 after a few months. Before that, I had the nutorious black screens - no display, but the sound was still going.
I've run it through Furmark and Unigine Valley, and it restarts after a minute or so, specificly when the core temperature hits ~63C and VRM 1 hits 70+ (VRM 2 is sitting nicely at 55C). It can happen in ANY game, even on less demanding ones like Dota 2 - which is when I actually found out about the problem. (Although more common on more demanding ones like BF4 or Crysis 3).
The black screen issues I had before happent on higher VRM1/Core temps, but probably because of the constant restarting I don't get those. (Or maybe it's a different form)?
I've done a memory test, and my 8GB of RAM is working properly. Prime95 runs with no issue for a couple of hours, and CPU temps peak at around 65C. I've tried increasing the power limit to +50 - what happent on Valley is that the card stopped working but after a few seconds started working again, and kept repeating this until it eventualy restarted.
I've tried reinstalling the recent 14.4 and older beta drivers but nothing helped. I've played a bit with voltages with Afterburner, that didn't help at all. Even reducing the memory clock speed to 1100 and 1000 MHZ didn't help too. Tried legacy boot and other bios settings (gen 3 PCIE and what not) but that didn't help either.
I am 99% sure it's the GPUs fault, but I need some advice. Is there anyway to fix this? I would appretiate any help on the topic.
