How to Patch and Repair Drywall - Lowe's
Drive a drywall screw 1 1/2 inches above the popped nail head into the stud to reattach the drywall to the stud. Sink the screw head just below the surface of the drywall so it can be covered with spackle. Drive in the popped nail. Cover the sunken screw head and nail head with spackle until level with the wall surface.
