No DVD/CD Drive Showing

i was away for a long time so i do not know exactly what happened but the wife had let me know that the cd she had put in for my son was not playing so i aske her to look at "my computer" to see if the dvd icon was there but no. so i told her to go to device manager and uninstall which she did then restsart the computer. On restart the computer said installing driver for new hardware but it failed..have tried other ways of deleting then reinstalling but still i cannot use the cd/dvd drive..have even gone down the route of purchasning a new dvd writer but that did not work. by the way error code is" Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
