So, I have the chassis fans plugged into the mobo. The mobo is a asrock z68 fatal1ty professional series gen 3 with p2.20 BIOS. There is no option in the BIOS (that I can find) to set the sleep mode to S3. This mobo also comes with a Dr. Debug LED to report any errors, so when the fans go off during sleep the debug says nothing, when the fans stay on it displays 01 (Power on. Reset type detection (soft/hard)). I'm running Windows 7 x64, haven't done any overclocking or made any changes to configurations.
I've reset the CMOS, updates drivers, tried running without my VGA, and spent the better part of yesterday googling for answers. I'm open to suggestions and willing to provide any additional details. The frustrating part is that the fans *sometimes* go off!
Thanks in advance!
