I'm not sure if this is due to BIOS options, as I have messed with them a bit. So far I can only wake the computer from sleep if I press the power button. Also, when I force shutdown via the power button, after 4 seconds, the computer restarts.
I'd like it just to stay off but I'm not sure what setting would decide that.
EDIT: I was able to get it to wake from sleep via a setting in the bios. No problems there. Still wondering why it restarts after 4 seconds on a force shutdown?
I agree; first check your BIOS, then I'd check and make sure you seated your jumpers from the case panel to the motherboard correctly. This has always been a sore spot for me and until my last build always took me 2-3 tries.
