KA1 won't reboot normally

[nvme17]

I'm running a ECS KA1-MVP 1.0 and when windows goes to reboot it does not reboot, the cd-rom lights flash and that's about it, no video. If I power it down and turn it back on it boots fine

I have tried bios updates, clearing cmos (even taken battery out to let it completely clear)

Opteron 165 @ 2.4ghz (8x300htt). 24hr prime stable.

It does this even when overclocked by only 20mhz. If I reset the bios and leave it at stock settings it will reboot normally. Has anyone else had this problem?

Is there another crossfire board I should be looking at incase this is a bad board?

I'd try a power supply swap first. Any power supply can go bad, or not be adequate for your system.

Its a new Antec True 550, but hey you never know. I tend to forget the easy things first! Thanks.
