Did you correctly reconnect both the data and power cables to the DVD drive? Check both cable connections at both ends. Be sure to power off, unplug and press/hold power button for ~15 sec before working inside the case.
Then reboot and open BIOS setup (Press F2 before Windows starts to load.) Is the DVD drive recognized in BIOS?
Possible the DVD drive failed...?
