I have a Toshiba Satellite M45-S265 booting from PC-Doctor Service Center 6 w/ the Multipurpose USB device connected. I'm booting off the cd, since there is no option to boot from usb. When I click on any of tests, the system halts at authorizing and never goes through any of the tests. Sometimes when I try rebooting, for whatever reason the keyboard fails to work. No button works and I have to press the power button. Also, the system shut down on it's own a little while ago, I'm guessing because it started overheating.
