Running Dell Vostro 200, approximately 12 months old with Windows XP Pro, 2G of RAM. Just replaced power supply yesterday upgraded to 500W because I had been ripping my CD library to an external HD, when all of a sudden, whenever I would insert a CD into the CD/DVD burner, the computer would reboot before it gave me any choices. I attempted to update drivers and that did not work. The DVD ROM drive works find for ripping, just the burner causes restart. I tried switching the SATA cables on the drives and still got the same result. Should I try replacing the DVD burner? I ran diagnostics, said everything was find, Device Manager says everything is fine, ran Check Disk, no errors. I don't know what else to do other than try to replace burner and if that's not it, call in a professional! Any other ideas?
