I have a pair of new HIS 7790 cards. They used to be in my Thuban / 990FX rig, with an Antec Earthwatts 650W PSU. Running the 13.9beta5 (?) drivers, they were throwing driver errors, running distributed computing. So I installed 13.12 WHQL drivers, and they seemed a lot more stable. I could crunch, and wake them up most of the time.

Fast-forward to last night. I souped up an i3-3240 computer with an Enermax NAXN 350W PSU (single 6-pin PCI-E), 2x4GB GSkill Area DDR3-1600 RAM, WD 500GB Black drive, and one of the 7790 1GB cards.

I'm running BOINC, and doing Einstein@Home, which uses ATI GPUs. With GPU-Z open, it shows 1% GPU usage, temps 30-35C, core clock bounces around, seen it hit as high as 400, and memory clock bounces between 150 and 1500.

So it doesn't appear to be overheating. I have the computer set to sleep: none, and monitor sleep: 10 minutes.

If I am running BOINC, I can let it go to sleep, and then within a minute or two, I can wake it back up again. If BOINC isn't running, I can let it sleep for an hour and I can wake it up again. But with BOINC running, several times so far, I cannot wake it up if I let it sleep too long. (How long, I haven't determined yet.)

However, judging from the HDD light, it's still crunching, even when it won't wake up. When I forcibly powered off, there were no GPU fail or recover errors in the Event Log when I powered back up.

I'm connected via VGA out, to a 32" Westinghouse LCD TV.

I'm having the same issue with my dcu 7770 and 13.12 whql . I think it's a driver issue tbh

I know the new drivers have a fix for black screen issue 290 owners are/were having. Maybe they broke something in older cards.

I would summit feedback to amd on their driver page and try some other drivers.

My XFX 7770 does it too. It was never fixed for me so I just disabled sleep.

I have disabled sleep on all of my GPUs that do crunching/folding. No reason for it really and it causes more issues than it fixes. Meh. My HIS 7770 has been doing it since something like April.
