Games Minimize To Desktop Then Crash

I'm currently pulling out my hair. I'm having a slew of odd behaviors coming from my PC while gaming:

-Intermittent screen black outs, with the sound remaining. After three seconds, the image comes back.
-Game image staggers, odd stutter sound from my speakers and the screen blacks out. After a few seconds, a return to desktop. The game audio continues to run fine, but the game in question is 'Not Responding' according to task manager.
- GPU clock rate varies at high loads, despite having 'preferred maximum performance' set in Nvidia Control panel (seems to happen mostly in Assassins Creed 4).

This is happening almost all games including AC4:Black Flag, Arkham Origins, Arkham Asylum, Mass Effect 2 & 3. Don't know why, but no crashing issues with Deus Ex: HR or Tomb Raider (2013)... yet.

Here's what I've done to diagnose/remedy the issue:
-Ran memtest86 to verify the integrity of my RAM.
-Ran several benchmarks on my GPU without crashing (crashing on games seems to occur an hour or two in gaming)
-Clean installed my graphics drivers
-Verified the game cache/files for all games being played at the moment.
-Monitored my temperature settings: My card stays no higher than ~70C.

SPECS:
ASUS Z97-AR mobo
i7-4790k
EVGA GTX 780 Classified
16GB DDR3 Dual Channel Crucial RAM
500 GB SSD
1TB HDD
CX750M Corsair PSU

Once a minimize to desktop/crash occurs, it happens more frequently if the game is restarted. Shutting my computer down and letting it 'rest' seems to "fix" the problem temporarily. This sounds like a temperature issue, but all of my temps seem normal. The issues were reduced when games were installed on my SSD, but were not eliminated entirely.

Insight on how I can catch this problem and diagnose it would be most helpful.
 
Sounds like a PSU/GPU issue for me, a GPU only throttles down it's frequency while on load either by overheating (which you've ruled out) or when it's not being able to draw enough power from the PSU, I've read several posts where people complains of various issues related to the CX PSU series, it seems they're built with low quality capacitors which shows its problems after a few months of use, maybe that's your case.

Best way to find out is to test your GPU with another known quality working PSU.

Haha, crap. I just replaced a sub-par 500w PSU with this one :)

Do you have any suggestions to reliable, quality PSUs?
 
Largely depends on your budget, but because of your GPU I'd say aim for at least a 700w unit, Silver 85+ Certified from a known brand like Seasonic, Antec, XFX, Corsair (except of course their CX series) and Superflower.

If you google around a bit there's a tiered list of PSUs here at Tom's, aim for a Tier 1 or Tier 2 PSU, I'd say invest now in a Tier 1 if one day you decide to SLI your current card.

Hey thanks for the suggestion, RaD. Replaced with an EVGA 850w psu. Still having occasional minimization issues. Looked in the windows event viewer, it shows that the Display Driver nvlddmkm stopped responding and was recovered. Happened twice, back to back in the period of a second.

This is clearly an issue with the driver, but is it a GPU problem or something to do with Windows...?
 
Google around to see if your current driver version is causing similar problems to other people that also has the GTX 780, nvidia tends to have this kind of issues with some models and sometimes an older driver will do the trick to keep it stable.

You say you still have occasional issues when minimizing games, but stuttering, black screens and such have stopped to happen or still suffering even with the new PSU?

Yea, the same issues (games auto-minimize, stop responding), accompanied with a log warning in Windows Event Viewer that state the graphics driver has stopped responding and was recovered. Actually, two identical warnings, back-to-back.

I did notice that my motherboard BIOS was a very early version, with several BIOS updates coming out after the fact. I totally forgot to update date it when I did a new build. I'm gonna flash my BIOS when I get home and see if that's the ticket. I'll report back with my findings.
