As described, a flat screwdriver will do the trick. Simply insert the screwdriver between the eprom (with the white stickers) and the socket and gently turn the screwdriver. Then do exactly the same thing to the other side of the eprom. This will lift the eprom. Then simply push it back into the socket. You don't need to lift the eprom too high.

Looking at the image, it does look like an Eprom issue as the background graphics are not correct.
