I have a Dell Dimension XPS, XPS Gen4, Pentium 3.6ghz, 3gb Ram, Windows XP Pro, service pack 2. I had a windows error and needed to repair the windows installation. Did that, and now it appears that I have lost my DVD and CD drives. The lights on the drives come on and all and they open when you press the button, but the computer doesn't see them. They don't show up under the device manager. Doesn't see them in the bios either. I've tried unplugging the ribbon cables from the drive and re-booting, and the computer sees that something is missing. Re-installed the cable and re-booted again, hoping that computer would think it's new hardware. No change. So I am at a loss as to what is wrong. Any ideas or suggestions would be much appreciated! OH, my technical knowledge of computers is average at best. I mean, I know enough to be dangerous!! LOL LOL But if your suggestions are highly technical, I might need a more simple and easy explanation!!! LOL LOL Thank in advance!!
