Hi....I'm not exactly a newbie at computers, but I have done more software than hardware. I am fixing a friends computer....it had 18 trojans on it, causing it major problems. The decision was made to format the computer and reinstall OS. While formatting, the computer reported bad clusters on the hard drive and repeated attempts to reinstall OS has been nothing but trouble (continuous reboots, blue screens, etc.) I have an old hard drive that my son took out of his computer and gave to me and I want to know IF and HOW I could go about putting it in instead.
Thanks for any help given.
