hi sorry if i put this in the wrong place but i am new here i was wondering if someone could help me with a problem i have i have recently installed Vista x64 when i had finished my dvd drive was no where to be found not in device manager not in the bios not anywhere i know it is not vista because i installed it as a dual boot alongside xp and it don't show up on xp either.Vista is working fine except for the DVD drive if i do a cold boot my dvd drive will show up until i try to use it and then the whole system freezes and i have to restart then it is gone again. i am not totally sure why this is happening but when i got my pc last year i had to re-install windows and this happened to it then as well(with xp)so i don't think it has anything to do with the OS or hardware(possibly)i have tried to install the latest drivers and firm ware with out success i actually tried the dvd drvie on another pc and it works fine and it is not the sata cable that works fine as well anyway i think i have said it all my dvd drive is a pioneer not exactly sure how the model i can't check because it isn't showing up lol i will post back the number when i can check the actual drive
