I own a dell inspiron 8600, and suddenly the cd/dvd drive (philips cdrw/dvd cdd5263) has stopped working. when i put a dvd or cd i have the usual whiring sound, but the computer does not recognise the drive is there. When i go onto the safely remove hardware button, it cones up with a the drives name and a yellow warning triangle next to it. i click on that and it comes up with a page saying: Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39) Click Troubleshoot to start the troubleshooter for this device. I click on the troubleshooter button and it takes me to a microsoft help page saying i should unistall it using the device manager, i do this, then it says i should reboot th pc, i do, nothing changes. i says i should then run the add hardware wizerd, i do, i follow the instructions...... nothing! please help!
