Flickering black screen, buzzing, crashing, GTX 760

[kewlbootz]

Lately, whenever I game (most notable while playing Smite), I *usually* eventually get a random black screen flash, sometimes a total freeze that I have to ctrl, alt, del to get out of, or, the worst, the audio freaks out, buzzes loudly, and I have to restart my pc. A lot of games seem to work okay for the most part, though they can crash, with no recognizable pattern.


Specs:

Windows 10
i5 6600k @ 4.4hz
GTX 760 SC
MSI Gaming M5
HyperX Fury 16gb @ 2133
An old HDD (tested with SpinRite and CrystalDiskInfo)

Here are some things I've monitored/tried:

-Reinstalled Windows 10
- Memtest: no errors, got new RAM nevertheless, still no errors
-Temps: GPU doesn't go over 60, CPU hovers around 50-52
- Bad GPU: RMA'd my 760, just got a new one
- Underclocked gpu
- V sync on/off
- Made sure my monitor is 60hz
- set card to maximum performance in Nvidia control panel
-It's not dust, it's new
-My 740 worked fine with no errors
-Replaced my old PSU

There's no .dmp file.. I'm not sure what kind crash I'm getting or what it means, and my Google-fu isn't doing much for me.

Any help/advice would be appreciated

What PSU do you have now?

Rosewill Quark 750. I had assumed the psu was the problem. But, it's definitely enough power, and a solid rating.

It sounds to me like a PSU problem. The documentatiion on the 750 Quark says it's "Intel 4th Gen CPU Ready," which does not apply to your new 6th gen. Skylake. I checked the 12v rail power output and it LOOKED like it should work, but it sounds to me like your PSU isn't able to supply even power to your other components (especially since this problem usually kicks in during a high-usage activity like gaming).
