HELP!!!! The Hard Drive in my lads Dell PC went and died. I got a new one and put it in, used the Dell Reinstallation CD to reload Windows XP. All looked good, and Windows XP was on the system. Put in the Drivers CD and loaded the soundcard driver. Hit re-start (as it told me to do) and then found that the DVD drive and the DVD-R drive are not recognised. The motor turns and the lights flash, but nothing else. I tried to 'install new hardware' but the PC didn't tecognise any optical drives. I know they work 'cos the reinstallation disk worked! What have I done wrong and how do I fix it?
