With computer components, early failure usually means a chip problem. But for thoroughness, boot back up to the BIOS, and on the CMOS page check to see if the BIOS recognizes it. If not, check to make sure the data cable is seated tightly. Remove and insert it again. These non clipped SATA terminals can easily move with heat or more commonly vibration motion.
Then boot back up into Windows and in the Device Manager, check to see if the OS sees the DVD-ROM device.
If not, then back it goes. Lite-On are very good DVD burners, I have several.
