IIRC I would get a "give root password for maintenance" message. Since there 
is no root password, this might be a problem. Perhaps a flaw in the Ubuntu 
way of doing things. 

I still think the PSU is the least likely of all the possibilities. I fear you 
will ultimately discover you have a bad motherboard. I'd still check the PSU 
though.

Something I just thought of: If your mobo has "fake" RAID, that might be 
causing problems. Try going into the BIOS setup and disabling any RAID 
functions. I once saw a mobo that worked with Linux only if the fake RAID was 
enabled, not intuitive but it worked that way.
