Immediately after getting in-game (loading a save file for Fallout 4, Witcher 3, or Skyrim and getting in-game or entering a match of League of Legends right after the loading screen - no problems on menu screens) I briefly hear a strange noise and both of my monitors go black and display an "Out Of Range" message. I still hear in-game audio and I hear usually hear a Windows notification, but as both my monitors no longer display anything except for the "Out Of Range" error. My computer continues to function normally and I any video/music continues to play, but my monitors never return to normal, forcing me to restart my computer.

I've had issues with my computer not turning on (PSU fan was spinning, but no lights/other fans were working and Windows didn't start). I've run MemTest to check for memory errors as well as Windows Memory Diagnostic. I've also had a brief "Nvidia display driver stopped responding and has recovered" error that resulted in a black screen with a "No Signal" message being displayed on my monitors (this is the only incident I've had where this has occurred, not sure if it's relevant). I don't know of anything graphics card related that might be causing this, but it wouldn't surprise me if it was a graphics card issue or a PSU issue.

Power Supply: Corsair CX750M
Graphics card: GTX 970
Memory: 32GB DDR3
Processor: Intel i7 4770k
Motherboard: MSI Z87-G45 Gaming
Storage: Samsung 840 EVO 250GB SSD, Seagate 1TB HDD

Any help would be appreciated, thanks in advance

Seeing CX in the model number of the PSU makes me cringe a bit ... seen several units that fall outside of the ATX spec which could cause the problem you describe.

The fact that all seems fine and dandy until you add a significant load to the PSU / GFX card points to your being correct about it being PSU or GFX card. Unfortunately without a "spare" of one or the other, you are in no position to troubleshoot. If you can't get a game to load, I think Furmark isn't going to run either.

The easiest option is to pull the card and install it in a known working machine with known good PSU.

Of course if you haven't shut machine down and pulled / reinserted tall cables (at both ends) and the card (don't forget to release locking latch), you...

Sounds to me like your GPU may be failing. Download Furmark and run the stress test. See if it crashes. Reinstall your drivers. But the big thing that makes me think it's the GPU is the fact that your computer won't even POST sometimes when you turn it on - at least you don't see it, so I think you may be having problems there.

Could the GPUs lifespan have decreased because of the low quality power supply you own? Yes, but the imminent issue seems GPU related if not GPU software related.

1. Uninstall all GFX drivers and nVidia utilities
2. Use ccleaner to check registry. Uncheck all the boxes and then check just one box at a time and "scan for issues"
3. Uncheck all boxes and then check ONLY those entries that say "nVidia" in it, when found 'fix" selected issues.
4. Reboot and install latest drivers.
5. Check windows display / advanced settings for refresh rate
6. Since you can get into game menus, use lower resolution

Also, check Event Viewer / Windows system and applications logs for any warning (yellow icon) or error (red icon) issues

It just seems too fishy to be the PSU to me. I mean, as soon as his GPU starts doing the 3D rendering and computation, it blacks out. If it was a power supply issue, I feel like Windows wouldn't still be working (you know it is because he can hear it) because that same 12V would cause issues with the motherboard and CPU. Sounds like the card to me.

Except he says there are times when he turns on the PC and he gets no signal, doesn't even get a POST screen, so this issue seems to span across a broader spectrum than strictly games.

His computer is not rebooting. The screen is turning black when the game starts while Windows still runs, as he can hear through the speakers. Such as the notification which is probably an issue with the display driver notification.

Not unusual, after system freeze and restart

That's why I suggested, since he can access game menu screens, setting a lower resolution than the monitor can handle.... tho for several games to suddenly jump to a new resolution w/o user intervention would be ... well weird. Another thing that comes to mind is ya using toasty strobelight utility which requires selection of 120 hz on 144 hz 1080p monitors.

Yes, it's a perplexing problem, made all the more difficult with missing information and lack of options / spare parts.

After arguing with EVGA for 18 months (20 calls, 5 RMAs) about a card that could not remain stable at the "as advertised / as delivered" core speeds, (they blamed MoBo, <emory, PSU, etc) I put two Asus cards in from an upcoming build and overclocked them 28% ... they sent a reference next gen card that's still in use ... but it ran at the base nVidia clock speed and was still faster than the preveous generation FTW

Sorry for the late response - the problem ended up being the driver. I uninstalled and did a clean installation of both the drivers and the games and everything is working fine now. Thanks for all of your help, much appreciated!
