Lg DVD GCC - 4521B, Suddenly Died!

Hi All, First post and that yay!..
d problem is a dead dvd drive. i went to update the firmware on the lg website, downloaded and was a bit into the installation of the firmware when all of a sudden a power cut. (Irelands a dodgy place) ever since the drive is completely dead, the pc wont even boot if its connected. no lights,sounds. nuffin.
Im pretty sure theres nothing i can do about it. but hey, mutiple minds are better than one. Any views greatly appreciated.

Sorry, man, if your comp wont boot the drive is dead without ability to repair it. But don’t give up yet, try it on another computer. I’ll try to think something…
