Dvd-rom Drive No Longer Showing Up,

CD-rom Drive not showing up or loading CDs? PLEASE READ EVERYTHING BEFORE ANSWERING!!! For some odd reason my cd drive stopped working after doing a system restore, -ive undone the system restores, tried a different one, tried going throug device manager, found the drive and uninstalled it, to be reinstalled by the system, still didnt work The most common solution ive found: ive also tried the regedit solution to delete lower and upper functions but i cant even find a lower or upper key, at one point there was a lower function, i deleted it but nothing happened and now it doesnt even show up, ive tried reinstalling the driver because that was when i first saw the lower, but still nothing

i know my cd rom is not broken or the wiring is not a problem, ive been having a few problems with my laptop lately, so i know its just technical problems, thats why i really want to do a system recovery, to not have to deal with this again for awhile, i finally decided to do do a system recovey to delete all files and start from scratch, but still nothing! There was no installtion cd for my windows vista, so i just did a recovery to reset everything back to the way it was, tried using my recovery discs that i made when i first had the cd, the drive still cant read it, even after i did the recovery

Computer : Im using Windows Vista HP Laptop DV9700 series to be more exact - and im passed the warranty, stupid hp has no technical help for free, called them last week abt why my webcam wouldnt turn on and they wanted to charge me 50 dollars just to help, when i know its not even really broken just a tech glitch, luckily i fixed the problem with the webcam
