So over the weekend,I've been using another computer to do what I can. Thank the gods for webmail. Though it *did* hurt not being able to get to my Juno e-mail.
Tonight, C finally got it working again. New case and power supply, but same old computer. Good thing we kept the install CDs up here, and not in storage -- there was a little bit of diciness when it needed the video and audio drivers, but everything's back to normal now. Yay! :)
