i have put a new dvd rom drive in my computer everything seem fine but when i went to mycomputer the drive wasnt there rebooted still no drive so went to device manager and its not thier so i use add hardware wizard which found nothing so then i pick it from the list in the wizard and it says it working fine looks back in my computer thier it is all working but it goes again next time i reboot i hoping someone out thier can tell me whats up as it is doing my head in

Have You allowed XP to detect the new hardware? this calls for a couple of re-boots. while the box is off, disconnect the data and power cable from the dvd drive, then turn on computer, then turn off again, re-connect the drive, turn the computer back on, and see if XP will detect it.

also check it has been recognised in the BIOS. if its not in the BIOS, windows wont stand a chance! Simon If at first you don't succeed, hide all knowledge you even tried.

Also, you may have to check the jumper switches on the back of the drives. Is the new DVD drive on the same cable as your hard drive? If so, make sure one drive is jumpered as "Master" (usually the hard drive) and the other as "Slave." If your new DVD drive is on a data cable by itself, you may have to set it as "Master" on the secondary IDE channel. (You should see information in your BIOS concerning drives on the primary and secondary IDE channels.)

its on the same lead as dvd writer writer is master and dvd rom is slave its in the bios when it boots up i have done all of the above. it is in the add hardware list as i said and as soon as i click on it it appears in mycomputer. and every where else it should be. i have also tried uninstalling it and when i reboot windows find it ok it just forget about it on next boot up
