I have a Supermicro X8DAH+-F-O board. I was able to get it to POST with a raw hard disk. It took about 30s to 60s for the power LED to illuminate, and then another 30s or so for POST (beep and Supermicro logo). I hear this is typical.
I installed Ubuntu 11.04 server on the hard disk, and rebooted when asked. Now the system will not POST. One time, I got the power LED to come on, but no beep and no SM logo.
I turned it off on the back, back on, and then tried powering it up again. After 5 mins, no power LED, no POST, no beep, nothing. All of the fans kick on and they seem to consistently running (not revving up and down) but nothing else.
It seems unlikely that an OS install would kill a motherboard or power supply. What else could be going on?
