I've got a PC that had it's hard drive crash. This PC doesn't have a CD-Rom or floppy drive, so the replacement hard drive I bought had to be put in another CD to have the operating system loaded. Well, I loaded the new OS on the hard drive. But when I moved the new replacement hard drive with its working operating system over to the PC which needed it, the computer wouldn't boot past the "Starting Windows" screen. What else could be wrong with this PC other than the fact that it needed a new hard drive? Or, could the original hard drive have been fine all along and something else is the problem?
