Just got this new motherboard, and it works fine except for these power problems. If I try to put it to sleep, it'll sleep for like, 10 seconds, and then reboot. At first I thought it was being woken up by the NIC, which has happened in the past, but then I noticed that it wasn't waking from sleep, it was restarting.
Similar thing happens when I shut down. It'll stay off for a few seconds, and then it'll turn back on.
