Please, I need help from the board on this computer problem I'm having. I have a 5 year old HP desktop that I upgraded with a DVD burner about two years ago. It worked fine for a while but now is not accessible in Windows. I swapped the original CD Rom drive back in and it worked just fine. Swap the DVD drive back in: No workie. I'm using Ashampoo for my DVD burning program by the way. (Or at least I WAS) The drive will show up in Windows Explorer but not work. I've set the switches on the drives to all possible combinations (CS,SL,MA) with no success. The drive WILL spin up when I insert a DVD or CD however. That's the confusing thing, it worked just fine for a while then stopped. The only thing I can think of is either the BIOS needs updating or the Drive is no good. What do you guys think? Thanks in advance.
