Alright, figured I gotta ask somewhere if anyone has any clue what so ever what this might be.
So, first off, my PC functions more or less flawlessly in normal use - I can use it for 12 hours straight, I can play games for 12 hour straight, I can watch cat videos for 12 hours straight, it doesn't matter, it doesn't miss a beat and works great.
Enter the bizarre: If I leave my computer on overnight, when I come back and wake up the screen (the PC itself never sleeps), the image is distorted. Like a weird crosshatched distortion - but I can see the mouse moving, applications running - the PC is technically "working" - I just can't see a damn thing. Problem disappears if I restart.
I've had this happen maybe a handful of times now - and it ONLY happens if I leave it alone for a very long time. And heck, the computer isn't even "idle" necessarily, it might be running a backup, rendering a video, whatever, doesn't seem to matter. When I come back and wake up the screen after 8-9-10 hours or whatever, the image is distorted until I reboot. However, it does seem to function just fine otherwise - it's just the image on the screen is all fudged up. But the computer is still happily doing whatever it was doing.
I can't really isolate what the problem is. Anyone got a hunch what the problem might be, or observed a similar problem?
Not sure it matters but the specs are as follows;
Win 7 x64
780Ti x2 in SLI
Intel i7 4770k
32GB RAM (Corsair Dominator Platinum)
Asus ROG Swift monitor
- Hefty custom water cooling loop, nothing gets above ~50*C under normal use, GPUs never go above 50, ever. Doubt temperatures are any cause for concern.
Nothing out of the ordinary per se. Drivers are up to date, yadda yadda, the obvious things are in order. I have tried a full Nvidia driver cleanup and re-install.
Absolutely no idea what could cause this, myself.
