As the title suggests I'm having problems with my ASUS GTX 780 Direct CU II OC, or rather have been having for some time. I sometimes crash out of games and receive a "DX11 device hung" error message. It happens repeatedly in Battlefield 4 and used to happen in Hitman Absolution, The Evil Within demo too. I get regular crashes in Black Flag although the error message simply says the executable has stopped working (I've followed all the advice relating to save game issues, turned off AA etc).
What is unusual is that the crashes are quite irregular: sometimes I can play for hours before a crash, at other times for only half an hour. Just as curious is the fact that on occasion the screen will go black with the game still running in the background, after which alt-tabbing back to the game allows me to continue unhindered. Also when the latter occurs within the same session I won't seem to encounter the more usual crash, as if this occurs instead, something I find very puzzling.
It only seems to occur in fairly intensive games, I had run into crashes playing War Thunder but disabling my CPU overclock rid me of those. I've run Memtest86+ and all seems okay after several hours. Running Furmark briefly (20mins or so) doesn't replicate the problem and temps push no higher than 65c (although the benchmark seems to hitch once every second). I run Windows 8.1 with a high performance power profile (have used balanced too).
Could this be a PSU deficiency? I have a 3 year old Antec True Power New 650w and use two separate leads to power the card (it has several rails capable of outputting 24/26 Amps each). Is there any way to determine if the card is starved of power?
The rest of my system is as follows:
i5 2500k @ stock
16gb Corsair LP 1600 9-9-9-24
Asus P8P67
Samsung 830 240Gb SSD
Any help would be appreciated. I run the card at it's default factory O/C. I didn't notice it at the time but I think I've had this issue since first owning the card and across various driver sets but as it only occurred in very few games and BF4 was initially a buggy mess I didn't really notice until recently. I never had any such problems with my previous GTX680.
