...the CPU unit. What gives? I have a e-machines W3118 Desktop PC, and recently the computer has been displaying an error message when I try to use the DVD/CD-RW drive to watch a movie, rip a CD, or burn a CD. It says it cannot detect a CD-ROM device. I wanted to know how can I get my machine to recognize its own disc drive, and is it possible for me to burn DVD's even though I don't have a DVD RW drive.
