There's probably a better forum for this question, but there seem to be plenty of knowledgeable people on this board.

I've got an ASUS HD7970-DC2T-3GD5 driving 6 monitors.  It behaves just fine for the most part, but the card has a hard time waking back up.  The computer is set to never sleep, though the displays are set to power off after 10 minutes.  If I try to wake the monitors up after 20 minutes, it usually works just fine.  If I come back a hour or two later, I get displays that wake up with a black screen.  Ctrl+Alt+Del doesn't do anything - the computer seems to be unresponsive.

Some weird things:
- If I use Remote Desktop to control this computer, the Windows login window will show up on the displays right away.  I can then log in and the computer operates normally.  If I do this several times, Catalyst crashes.  The system behaves exactly the same whether Catalyst is running or not.
- I've noticed occasionally the display will try to sleep after 10 min, then wake up, fall asleep and wake up.  After it does this a few times, the displays will sleep normally.

The box is running Win7 x64, 1200W CoolerMaster Silent Pro PSU.  The card is running stock.  Any ideas on how to fix this issue?
