I've had this PC for half a year, and the specs are:
CPU: Intel i5-4670
GPU: Sapphire R9 290 (Came with stock cooler, but I installed the Gelid Icy Vision Rev.2 custom cooler on it)
PSU: Corsair CX750 (Non Modular)
Motherboard: Gigabyte B85M-HD3
HDD: WD Caviar Blue 1TB
OS: Windows 8.1, with the latest software updates.
My case has acceptable ventilation, Got 1 front intake, 2 top intakes and 1 back exhaust, and I am getting somewhat acceptable temps when gaming/stressing - My GPU core doesn't go above 70C, CPU cores usually max at 60C and GPU VRM1 is maxing at 80C and VRM2 at 65C. (One is notoriously hotter).
The problem is that my PC never actually manages to reach those max temps, because it immediately restarts when the GPU Core hits ~63-64C and the VRMs hit ~70/55. It can happen in ANY game, even on less demanding ones like Dota 2. (Although more common on more demanding ones like BF4 or Crysis 3).
I've never had this problem before, although I did have the famous black screens on my R9 290 (I should have RMA-ed before I installed the cooler, I didn't give one black screen much attention), but I've never had then since this problem began (those were caused my the faulty Elpidia memory overheating, I assume), probably because my PC never actually survives long enough for the VRAM to overheat.
I've ran Furmark and the PC restarted within a minute, as soon as the core temp hit 64C. I have no idea why on that specific temp - Maybe it's just a coincidence, and something different malfunctions.
I suspect that it's 99% the GPU, but I have no idea what else can cause this issue.
Any help and advise on the topic would be appreciated!
