The shrinking of the wooden frames behind the drywall and warping of the wooden frame can cause nails and screws to become loose and pop out of the wall. If a screw is popping out, you can either see a bump in your wall about the size of a quarter, or you can see the head sticking out from the wall. Bumps and holes in walls are not something that people like to look at. To fix them, get a screwdriver, manual or electric, screws, putty knife or spackling compound, fine paper, paint, and a brush.

Try to drive the screw in further with a screwdriver. The head of the screw may not rotate as far into the wood as it should. If that happens, you will need to carefully remove the head. No matter whether you drive the nail further in or remove the head, it is important to release some pressure from the screw. To do this, place another screw about an inch above the first and the third one about an inch below the first. Fill the holes with the putty knife or spackling compound and allow them to dry for between two and four hours. You will need to sand off any excess and then check if another coat is needed. It tends to settle in as it dries. Apply another coat of spackling compound, let it dry, then sand and paint. Don't be surprised if two coats are required.

Screws can occasionally pop out of drywall, but they happen less often than nails. If you don't have the option, use screws to attach your drywall to start with. You'll be able to fix it later.
