Hmm, I don't know about what others will say but it looks like the kink in this system in the PSU. I am not 100% on this, but isn't the "Ultra" brand Tiger Directs house brand? I seem to recall seeing it quite often on their site. Anyhow if it works for a little while then dies, try a new (different brand) PSU. I think if you popped the cash on a Enthusiast platform it seems silly to me to cheap out on a house brand PSU. Go for Corsair, Seasonic, Antec, ThermalTake or Silverstone. However this does not explain why a BIOS reset (battery pull) helped solve the problem. But a higher quality PSU surely wouldn't hurt!
