I have a dell optiplex gx 260, it has a cd-rom, p4, and 2gb of ram. About a month ago the user plugged his heater into the power outlet used by the machine, resulting in blowing a fuse. The machine was turned off as a result. Upon booting up the cd-rom is no longer seen by the computer, in the bios it is listed as unspeified device or unknown. Well yesterday the hd crashed, can this be the result of a bad bios, if so any place to give detailed instructions on flashing the bios? If there are any other ideas that would be a wonderful help as well.
