Well, unfortunately the rig is set up at school, and I'm about to leave for home, so I want to leave it mining. As such, and because there may also be difficulties with booting, I don't want to risk reboots at this point. So I'll be back in two weeks and I'll work on it then. I'm thinking this is probably a mobo issue, and the booting issues mean the hdd is suspect too.
tl;dr I'm going to just leave it running at half capacity for two weeks until I get back. (I have someone in town who can come and get it back up if it goes down.)
