 We actually tried shutting off one of the computers, but it did not reboot. We've got others that give us a blue screen that says restart, and then you try restarting. It first pulls up the page that would seemingly be that screen where you can type in your password and all is right with the world, and then it just stops and reboots again and goes back to the dreaded blue screen. What's worse, dreaded blue screen or just a blank screen?
