I'm not expert, but it might be computer problem, because others don't have problems like you do. Try playing gta sa singleplayer, if it still freezes, then it's something wrong with gta (download another one from diffrent web page, if you don't have original one). If it freezes in multiplayer only, try playing on diffrent server. Make sure you disable any antiviruses that are running (except windows defender), they can steal you much RAM that will lead to freeze.
