I have an Asus P6T deluxe v2 with a Core i7 920 and 12GB of DDR3 ram. I am running windows 7 RC1 x64 and whenever I go to shut down my PC, put it to sleep or hibernate it will stay in the proper mode (sleep, hibernate, shutdown etc.) for about 20 seconds and then it will turn right back on. I have to flip the switch on the PSU to keep it turned off. Any help would be greatly appreciated.
