105 Help Needed

ONe of my trusty 105’s has quit working for me. It worked flawlessly for about a year. Now, however, it will not recognize that a disc is in it. I’m able to update the firmware, but it will not recognize any kind of disc, from DVD-R’s that it burned previously, to master DVD9, to CD or CD-Rs. The light doesn’t even come on when trying to read a disc.

I’ve checked all the obvious things with no luck. Swapped it into another PC with a working 105 in it, and the problem followed. It simply will not recognize that a disc is inserted.

Any ideas???
