text: after installing ram cd drive not working? anyone know how to fix cd drive after installing ram. i installed ram in two computers and the cd drives are not working both are dell computers.  2100 2300 models. check to see if you jiggled loose the cd cable.  both the ide and the sound cable.  too often the rams are behind the wires and you might have to move them to get to the dimms.  so if you had to, go back and check to see if the plugs on the ide and sound cables are seated all the way in.
