Thanks Ron, I was leaning towards that choice myself. I think that even if I had to keep the drive, and the old one was not bad, it would be more of a waste to buy the adapter which I would more than likely never use again.
I have not yet tried to clear the Bios, but wanted to report what happened just a bit ago. I went to support, and went to downloads. I downloaded the updated driver for my DVD/CD drive. When I opened the file, and ran the download, the DVD drive light flashed on and off during the entire download, and said it was succesful. I rebooted, but still same problem as before. Strange.
Thanks to all of you for taking the time to help me!!! Turns out it was the DVD drive, and I got a new one quite reasonable that seems to have fixed the problem.
