Solved: Had same problem. 32-bit Vista Home Premium would immediately resume after entering sleep/hibernate. Isolated culprit by selectively disabling services using msconfig. It was the DHCP client. Seems there is a conflict for the 790i motherboard due to multiple ethernet ports. Resolved problem by moving network connection from MAC1 to MAC0 (ie, moved the ethernet connector to the other connector on the back of the computer). Found it could also be resolved by disabling one of the ethernet ports (ie, MAC0 or MAC1) in the bios. Hibernate/sleep work fine now. Hope this helps.
