Ok, so reading the replies, tell me if I have this right: When the board goes through the initial POST, it gets to the VGA and stops. Since it detects a problem with the gpu (which is nonexistant until Monday), it stops the POST, and lights up the VGA led. Since the boot device led would have been next (and last) in the POST pattern, it lights up too. Doesn't mean that there is anything wrong with my hdd, it just means it wasn't able to get that far.
Is that about right?
