Dvd and CD-RW Drives don't work

My HL-DT-ST CD-RW GCE-8483B and my Samsung DVD-Rom SD-616E have both stopped working. I keep getting error #39 for both of them which is for corrupted and missing drivers. This may have been caused by a few power outages lately. My problem has been trying to fix them. I've been unable to find the proper drivers for download. I thought I'd found the right one for the Samsung on their site but when I try to run it I get Drive Not Found. I tried getting windows to find one for me but that didn't work either.

My brother brought over a USB Drive and tried to load the drivers from the install disk but the USB drive won't work either. Apparently the problem is with the drivers for the entire controller (whatever that means) and whatever CD-Rom I try to plug in will have the same problem.

What can I do? I will really appreciate any suggestions. Thanks
