You say nothing of your system, OS, installed software etc. Some more information would help to determine if it is an issue related to hardware or software, at this point it is difficult to say. Did the drive (system) run disks normally in the past? Again a bit more information.
Ok so I put disk one of Star Wars Knights of the old republic in my cd-rom and it registers it is in it and loads for a second or two then nothin happens and I even tried opening my computer and trying to install from there and it still doesn't work please help
