Is this a Random Motherboard or PSU Failure?

Hello. I was randomly my six years old Ivy Bridge system, with a kinda dated I7 3700K, 16GB G. Skill DDR3 2100mhz ram, Asus P8Z77-V LK, Seasonic s12ii 520 watts, EVGA GTX 1080 SC2- because the Seasonic don't have dual pic-e eight pin dongles and it was sufficient enough to hold on my power supply- encased in a 2012 Cooler Master Haf 912, and I know need to upgrade to a Ryzen refresh or wait 9th Generation is out- The latter is what I was planned on doing- and swap that insufficient PSU...but today, June 22, 2018, I've experienced signs of a motherboard or PSU failure. I was just idly using my computer to watch some YouTube video, its switches to HD in less than two or three minutes my monitor goes black and my GPU fans is spinning worse than a stress test. So I reset by hitting the power button, it did twice. I diagnose my ram with memtest86 from Passmark and upgrade to the latest GPU driver but they didn't solve the problem.



Yeah that sounds like a PSU failure and I stop using my PC until my PSU arrives. But there is another problem it could the motherboard or both of them: About five days, I experienced one of my front panel usb header gave me error say one of your USB port had malfunctioned and this device isn't recognize and four of six USB ports( two USB 2.0 and four 3.0) will work and two USB 3.0 below the Ethernet jack would immediately BSOD and restart the computer. I found a workaround with a USB hub and see if that a failing PSU or Motherboard or both.


P.S. I tried everything under every solution to try root out the problem, but to no avail. This totally disheartening I was planning to upgrade to a new 9th I7 9700K... But oh well.

Alright. Well, the most cost effective method is to test the graphics card in another PC if you can borrow one that has a decent PSU. Or borrow a confirmed working PSU that meets the requirements of the card (the latter option is the easiest). But your motherboard is damaged (dead and grounding USB ports will not work again and may cause damage if accidentally plugged in again), so I do suggest replacing the PSU and motherboard anyway.
The first part sounds like a GPU failure; but when added to the recently dead USB ports causing BSOD, then I'm inclined to agree that the PSU is going and killed those parts on the motherboard... hopefully it didn't also kill your 1080 just then.

Knowing the age of the system, you probably should be looking to upgrade if the motherboard is damaged and you're getting a new PSU anyway. That said, finding a new ivy bridge socket motherboard should be the minimum done to address the damage on your current motherboard.

Also: What do you mean by " I don't dual pin eight pin dongles"? The wording there confused me.
 
Sorry about, my Seasonic S12II doesn't two eight pin PCI-E connector but one and a six pin, so I had to settle for a specific GTX 1080. It has twice went to a black screen, GPU fan roaring while its still on. To temporarily relieve of the problems and not increase the chance of damaged components, I unplugged and stop using it...Hopefully, a EVGA G2 or G3 650w will resolved and I've no problems hopping on EBay to buy a used replacement or RMA a GPU if the PSU is not the culprit.

I swapped GPUs and my GPU Overvoltage Power Protection was going off for no reason. It was absorbing too much power in the first place, I've replace my motherboard and got a EVGA G3 850w on sale- Primarily, I want to overclock the GPU or CPU without choosing between the two- and my problem is totally solved.
