I just replaced a motherboard, it required a clean install of Win-7 and I forgot that the default is to set a 20 minute suspension. Of course, I cannot use that since I run a farm 7/24. I had 4 crashes in 6 hours of running my new system - EVGA 760 chipset with HIS 5850 and BOINC 6.12.13. I have not installed any other software so far.

I almost returned the motherboard as I thought it was defective until I realized it was suspending itself. The event viewer simply shows a bugcheck (crash occured) and previous to that, hours earlier, are statements about going into suspension.

Since I disabled the suspension, it has not crashed and I completed my first 24 hour burnin.

AFAICT all the devices are capable of being woke up after a suspension so I am guessing that one of my ATI app's: Prime, Collatz, Milkway, or Seti-Beta has problems when the GPU awakes from suspension.

I am just guessing but was wondering if any other users have seen this problem.
