Hello Everyone!.
I had the same problem but I followed the simple instruction by 'gvalklov' Thank you very much!
System
i7 950
6 x 2GB Dominator
EVGA X58 Classfied 3
ATI 5850
OCZ Revodrive 120GB on PCI-E
Win7 Ultimate 64 SP1 (6.1.7601 Win7 RTM)
It didn't wake up from either S1 or S3.
I upgraded BIOS to 83 but the problem persisted.
I could not uninstall SP1.
The hotfix above was not an applicable option for my system.
Finally I went to into Windows Control Panel> Power Options> Change Plan Settings> Changae advanced power settings> Sleep > Allow hybrid sleep >(and selected) Off. (Apply and OK)
Now my system wakes up as normal computers do.
