The other day i turned on my computer and whenever i put a disc or any other type of disc into the cd-rom and cd-rw and go into my computer to run the files or program, the drives are not there. The drives that are suppose to be there are the (D and (E drive. I typed them in run but it couldn't locate them. So i right clicked on the drives and it said they were working inproperly so. I check windows updates and I had all the updates. The error read, " Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged (code 19). What is the problem??? this is what i have LG-CD-ROM CRD-8483B and Mitsumi CR-4804TE. I also did a restore point but still nothing and I hardly ever mess with my registry. I appreciate anyone's help.
