I asked this question before but the answer I got didn't quite do it. Here it is: Most of the times I try to use my cd drive it doesn't work. Either the light on the cd drive goes on and it locks the computer, or the light stays off and the system thinks there is no cd in the drive. When you try to take the cd out by pressing the button nothing happens. One more thing - when the light doesn't go on I know the cd is turning because when you finally get the cd out after pressing the button a million times it's in a different position than when I put it in. Also I think it's nothing to do with the software.
