My electric power steering keeps cutting off on me it comes back when I restart the car. This happens after I make a turn it wont happen when I engage in turn my wheels must be straight. If I weave back and forth this wont happen. The fuses are good I did not jump start anyone. I heard the fuse box is in a shaky place and the fuses can shake loose I secure the fuse under the hood it still happens. There is also a fuse box on the inside of the car with a fuse for power steering the circuit board the fuse plugs into is not very secure.

Does anyone know about this?

Are all the fuse boxes in 2007 HHRs like this?

Attached is a photo is there a screw here?

The inside "Fuse Box" is not just a fuse box; it is the BCM or Body Control Module. Yes, the EPS inside fuse feeds the "Logic" circuits of the EPS, the under hood fuse feeds the MOTOR of the steering. AND yes there is a screw as in your original post - What is your question about it?
EDIT: The BCM is attached to a stamped sheet metal bracket - don't worry about it moving around. GM is just saving weight and thus gas mileage.

What you are describing sounds to me like a loose connection or a bad EPS logic circuit. Check the column for any loose wires, connectors, etc.
