After finally getting a backup tape drive to replace our previous one which decided to not work right, I've managed to a) probably blow another video card, and b) have finally realized that the power supply in our computer just isn't strong enough for what I want/need to do. Because I consider backups to be pretty darn important we'll be picking up new power supply to get it all working, and hopefully tomorrow night actually be able to start making backups! Fingers crossed!
