My desktop (OS Windows 2000 Server) has problem in startup. It had one DVD drive, and a CD-Rom drive -- on one cable. It worked fine before.
Several weeks ago, my son took the DVD drive off, then the problem began -- sometimes booting stopped (it seemed that the computer could not identify the CD-ROM), sometimes booting was OK, but we could not see the CD-ROM drive (from Windows Explorer).
Even the DVD drive was put back, the problem remains the same. Note: DVD drive works fine.
I think my son also touched the jumper.
Would someone please tell me how to correct the problem?
