Right i have been trying for the past 3 month to fix my uncles dvd+rw drive. I know to everyone that might sound out of the question to take that long but there are reasons. When they first showed me what was wrong with it which was every time you tried to record a dvd a quater of the way through the computer started restarting itself. I could not find out what was wrong with it untill i got a new dvd+rw drive for them and saw that the only disk drive that was inside the tower was set as slave. So i changed the slave to master and tried doing more dvd's. It got half way through transcoding and cut out but i realised that the slave being set at master was what was wrong with it because while i didn't know what was wrong with the recorder i installed ace codecs which after i set the slave to master and uninstalled ace codecs (Because the codecs with nero was conflicting with the ace codecs.). Everything worked fine after that and we had no issues untill he installed a vista transformation pack for xp (Which he installed wrong)(The OS which the dvd+rw worked on was media center edition sp2). Everything went to pot and i had to install xp home (XP home was the OS that was on this pc from the factory). I installed everything fresh so nothing should have went wrong but after i installed power2go express (Power2go express was already on the pc from the factory) it wont copy again and it keeps on restarting again like it did when the dvd+rw was set as slave and now i am exhausted of it and can't think of what else it could be. I am open for suggestions if anyone has any ? From DosKey
