Should I repair my desktop or replace it?

Larry's desktop broke and he took it to get repaired. He was told that his power supply blew out, and his processor didn't have a fan on it. Should he repair it? Leo says that power supplies are an easy fix. Larry's also considering buying a new Dell. Leo says that with Windows 10 out, the older the machine, the more problematic the driver support. But power supplies are a very common failure that's easy to fix.
