Ever since November, when I purchased a new EVGA GeForce GTX 970 Superclocked graphics card, I've been suffering power losses on a frequent but random basis. At first I suspected that my PSU had become faulty (It was a 750w Corsair TX Bronze-Certified Plus Power Supply) so I replaced it. I also noticed during troubleshooting my main hard drive had become damaged, so I replaced that as well. The total system build after replacing those looked like this.
CPU: AMD FX-4170
GPU: NVIDIA GeForce GTX 970
RAM: Corsair Vengeance 16GB (2x8GB) 1600MHz
PSU: EVGA SuperNOVA 750G2 (750 w Gold Certified)
MB: ASUS M5A78L-M LX PLUS
HDD: 2TB Seagate Barracuda
OS: Windows 7 64-bit Ultimate
Now, I continued to experience the crashes. I was quite frustrated. I assumed perhaps that the case fans' broken wires still being hooked in might be causing power issues with loose electricity. I haven't formally studied computing and am a simple hobbyist student, so forgive me if that seems an ignorant assumption. Moving on, I purchased a new chassis and set of case fans as well, placing the new system inside of there, no change. I became frustrated and finally decided to replace the motherboard and CPU altogether as well. The build now looks like this:
CPU: AMD FX-8350 BLACK Edition
GPU: NVIDIA GeForce GTX 970
RAM: Corsair Vengeance 16GB (2x8GB) 1600MHz
PSU: EVGA SuperNOVA 750G2 (750 w Gold Certified)
MB: GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX
HDD: 2TB Seagate Barracuda
OS: Windows 7 64-bit Ultimate
The problems still have not gone away, although they are quite minimalized. Inside the Corsair Obsidian Series 750D case, with two of the case fans going, the 2 fans on the GPU going and the Corsair Hydro 80i liquid cooling on the CPU I'm ruling out a real heat problem, though I haven't per say monitored temperatures. All thermal compound is new and fresh as well.
Detailing the problem itself, in the Event Viewer it simply says there was a Kernel Power Loss. There is no blue screen, no visible error or log of any kind I can see that tells me what's causing this issue. I've ruled out drivers entirely; I've reinstalled Windows 7 thrice over to alleviate the issue, and once Ubuntu, no change. It can happen while playing games, immediately after closing them, sometimes while browsing web pages. It's very sporadic and I don't quite understand why it's happening. I don't want to have to RMA my GPU, but that's where it's looking like the problem is.
If anyone knows better than I, I'd appreciate second opinions. I've tested the RAM with MemTest, to clarify on why I don't have any suspicions with it, nor do I expect this kind of behavior from RAM. Thanks.
