I am not sure whether this is a graphics card issue or a system issue, but I think it's an issue with my card (GTX 970 SC ACX 2.0). 
 
I was attempting to overclock using MSI Afterburner, and afterwards EVGA PrecisionX, and running Heaven to test stability, when I noticed this problem. Even when not overclocked and not using any overclocking software, Heaven crashes my computer within 20-30 mins, but faster when I increase graphics card clocks. The system seems to respond some of the time (the hard drive light flashes and I can flip numlock on and off),  but the monitor goes black and to sleep. I don't see any artifacts whatsoever, and playing other games such as Far Cry 4 for hours doesn't crash the computer.
 
I have an X99 system with an i7-5820k processor, Gigabyte X99-UD4 motherboard, 16GB DDR4 Ram, an EVGA Supernova 750 G2 PSU. 
 
Advice?
 
Thanks!

Yes, I'm overclocking my CPU, and it is stable for >24 hours on Prime95 and many rounds of Intel Burn Test. I don't think that the CPU is the issue, especially considering CPU usage during the Heaven benchmark is very low, but you're right, it is worth it to test. I'll report back on that later.

down clock your gpu 100 are 200 start with clock and then try the memory 
and see witch one it is.

yes rma time unless its the power supply might try another pc are power supply .  
but call and confirm with evga teck support so all goes smooth .
 
most cards boost more than spec .

Only have PrecisionX installed right now. I think the issue is the increased clocks since it's running at FTW speeds through the BIOS even though it was binned as an SC chip.
 
Edit: I submitted a support ticket. Thanks for all of your help. It is very unlikely it is a PSU issue because overclocking the i7-5820k uses significantly more power than FTW clocks on a GTX 970, and the system handles that fine.

You should start a support ticket through the support function at the top of the page. This will get you help relatively quick and get you back into the grind of daily fun.

Another black screen crash scenario.  Sorry to hear about your problem mrsausage. Make sure your mobo BIOS is up to date.  
 
When you get the crash, does your audio loop and then the system shuts down / restarts?

What happens when you underclock the system? The 3080Ti should have no problem hitting [link=mailto:1920X1080@60hz]1920X1080@60hz[/link] so I would test with nothing overclocked and looser timings on the ram to see if that helps. They can always be tightened up if it's stable.
