Do they know how to clean up a laptop and up date them.

Yes

Geek squad is the way to go

Just take it to the Geek Squad department and they can do that for you. It's best to call them and let them know what the issue is. Set up an appointment prior to going there. You can get service quicker. Instead of having to wait while at the store sometimes. But there is a fee for their service.

They should be able to. They have the "Geek Squad" that should help.
