It's nothing with his gta3.img I actually have the same issue with this on my spare PC (only with player skins and not with cars). I never bother to fix it because it's my spare anyway. Usally these kind of issues are related to faulty drivers or a broken GPU. Updating graphics drivers without deinstalling the old driver can bring a lot of issues. Try to use a driver cleaner that removes all drivers and left overs and install the latest version you can find.
