hello all.. I have a dell xps 600 , for about a year and a half. since I purchased this pc my dvd drives have been breaking... turn them into the warranty then they send me a new one.. I went through about 25 dvd drives and now my warranty is out , so I purchased two liton dvd burners , one broke and sent it in on warranty... now no warranty and after all this time I still can't find out whats wrong..... here we go.... the door on the drive is what is broken... the belts have broken in every drive that I replaced , when I put the liton in I checked and made sure they worked, haven't used them since then the other day I tried and the top drive belt was broken,,, I can't seem to find no info on why almost thirty drives have been put in here and the belts keep breaking... many thanks to anyone that can help or throw me in the right direction..... keith
