Personally, for me, a reformat and reinstall makes a lot of sense for most people. The reason I say that is that the majority of computer's that I've worked on don't have a lot of updates, no anti-virus/anti-malware program, maybe no firewall, and the person using it has been doing things like downloading music, visiting questionnable sites, and using generally poor judgment, and so there is a very good chance that no amount of repair will totally solve their problems. Oh, and these are on Dell or other namebrand systems that were purchased a couple of years ago, and have never had a reinstall.
I agree that you could fix them, but in my experience it is just much better to start from scratch.
