The computer wasn't doing ANYTHING before.. the Power button was lit up, and that was all.
The rig should at least POST with out the HDD connected, right? I was always under the impression that the HDD isn't used until after the POST. The post was all the board and the system test. And this board doesn't have a separate CPU power plug from the PSU. I've never seen that before.
You are correct, Antec. The hard drive only takes over at the very end of the POST, when the bootloader takes over and searches for the MBR (master boot record) on the hard drive. Like Nubbleet said, if you can find a manual that would help you.
