I have been working on this packard belle computer with xp. I fixed the original problem but now I have another problem the dvd drive does not work I have been inside the computer and checked the connections all seem ok. I have checked in devices manager and there may be a problem here the NEC rw dvd drive has an exclamation mark inside a yellow circle. I have uninstalled the driver and then booted up again I am getting the found new hardware message it has found the dvd drive but then I get another message saying a problem has occured during installation the device may not work properly, How can I find out what this problem is???
