My computer is making strange noises. Do I need to get a new one?

Episode 942 (45:29)

Yvonne from California
hard drive

Noises usually indicate a failing hard drive and that's an easy thing to replace. Yvonne can just backup her data, swap out the drive and then reinstall her OS and programs. There's no need to go to the expense of a new computer if that's all it is.

Yvonne also wants to know if there's an app for her Samsung Galaxy SIII that will take wake up her phone. Leo says that the proximity sensors may be blocked by Yvonne's cellphone case. That would cause the screen to stay blank.

She also wants a nice hands free option. Leo says using a Bluetooth headset would help. She could also just use the earbuds that came with the phone for this, and then she wouldn't have to pay extra.
