Windows 7: Odd issue; Black Screen, no HDD activity

Did you ever complete all those stress test that jumanji suggested?
I'm thinking that FurMark on the video card will give us a clue.

If all those test passed we are done to connections and replacing parts as a trial and error method. Time consuming and costly. If their is more than one thing causing this problem it gets very very difficult.

PwnFrnzy, as Layback Bear and jumanji requested, you need to run Furmark and prime95
Video Card - Stress Test with Furmark
Hardware - Stress Test With Prime95

With both tests make sure you keep a constant watch on GPU and CPU temps and stop the tests if the temps get too high.
We really don't know what you did when you say you put it through a medium/heavy load cycle.

On your temporary fix, try doing those fixes one at a time so you can tell which one actually fixed the problem. Maybe that will help narrow down the problem.

Video card was ruled out as the issue by running a spare I had, lasted two days before the issue resurfaced.
Issue occurred twice running Prime95.
Friend brought over a spare PSU and let it run Fallout 4 for 6 straight hours and absolutely no issues. Let it run Prime95 for two hours afterwards and still no issues.
New PSU is on the way, thanks for the help everyone, but that's a wrap.

Your problem could be a tough one to find. To me it smells like a power supply, which is very hard to diag.
I must have a high tech nose that works at long range.

All kidding aside; you stuck with it and did a great job getting it fixed.
