I have a Toshiba Satellite 1005-S157 that i accidentally dropped... When I plug it in and turn it on, the cooling fan in the back runs, but nothing appears on the screen. it appears the hard drive is working but the screen stays black. it doesn't boot up to BIOS. and it keeps giving 1 short beep about every 5 seconds. I've taken it apart and checked all the connections and they are good. If anyone has any suggestions PLEASE post.
