I have got a cd rw/dvd rom combine drive and another cd RW drive, which have been working well for ages. However, recently, neither drive is accessble. In the device manager, there are ! marks before these drives, and click on the properties, it said 'Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)'. Windows website help suggests edit registry, but it does not work. I don't have windows CD rom to reinstall the system (only a restore cd which would clear everything) And I can't even remove windows xp sp2 and reinstall it.
Please could someone help me solve this problem.
many thanks
David
