This lady who I work for has a Dell and it startd just booting to a black screen with a flashing cursor and that is all it does, so I checked the hard drive and it was all messed up and I though it was bad. So I put another hard drive, (used but works) just like the first except the new one is 40GB and the old 30GB, but both are WD Protege drives. The thing worked fine for a few boots then all of a sudden it does the same damn thing. I changed the drive to the secondary IDE channel but to no avail. I have never seen the like of it and I am stumped, but she is a sweet old lady and I really want to help her and get her back up and running. Thanks in advance.
