I have built a computer with a ausu p8p67 mb. I5 cpu . From a cold start the computer powers up for two seconds then powers down for four seconds then powers back up with a brief bios message "no hard disk found". The mb splash screen appears then it loads windows and the computer works great. What does the startup/hickup mean? Is there something to be done? -Nate

Hi TwinFrozr768,

Try reseating the computer components again and make sure everything is on tight, nothing is loose. Hopefully this will help you out.

The "no hard disk found" message pops up because the SATA/PATA controller is enabled in your BIOS when there is no PATA drive attached to it. If you are using all SATA drives, then go into the BIOS Advanced screen, 'Onboard device Configuration' and disable the SATA/PATA controller. The message should then stop appearing.

We need the info requested by dai to help with the power up/down issue.
