Both the dvd and cd rom drives have stopped working for some reason. I have windows xp home edition system. The drives have power, and the data cables are properly conected ( I tested the cables, they work fine). When I check in device manager, the drives an exclamation marks beside them and in the status area, windows says " the drivers for the device have been loaded, but windows is unable to find the hardware ". I have tried all I know and I have run out of solutions; please help.
