My friend has an old laptop that his dad gave him. It's filled up with lots of stuff he doesn't want and may have a virus on it. How would I go about cleaning everything up on the hard drive? I thought about doing a fresh install for him, but that means he'd have to find all the drivers for it afterwards which would probably be a hassle. Is there a way to wipe basically everything but the OS and core components of the laptop? I don't know the specs or model number currently, but I do know it's a Dell if that helps at all.
