Strange that you can't get into the BIOS, have you tried a different keyboard? Are you getting power to the DVD drive? Can you eject, etc? Can you boot off of it (before entering into Windows, some systems have a seperate key to change boot sequence without entering the BIOS like F11). Also try different Ribbon Cable, power cable, etc. If all else fails, buy a new one, they're extrememly cheap now days.
