I have a Toshiba Satellite A105 model S4384. When i turn it on, i see the Toshiba logo then i get a black screen with a message: " THDBA is compressed Press Ctrl-Alt-Del to restart. When i do, it just brings me back to that message. I am trying to do a factory reset but none of the options work....not the F1-F8-F12 or "0"- "C" nothing....i tried with the battery in and out....i have no recovery disc...i need help!!
