I have a Dell 4600. It has worked fine for the last 2 years. recently 1/1/06, both the DVD rom drive and the CD-RW drive spontaneously quit working. It is very frustrating because i have no plausible explanation for it. They were both working the morning of the 1st when i shut the comp. down, but when i rebooted a few hours later neither would work. I have the most up to date driver i can find, and i dont believe that i have a virus because i have done several scans. the device manager says that the drives are working properly and the troubleshooting guide could not solve the problem. PLEASE HELP.
