I recently got an all in one for Christmas and it only has 4gb of ram, would i be able to upgrade it to 8gb of ram at all? I've seen some people say i can and some people say i can't but i'm not completely sure who to believe. All i want is the ram to upgrade right now so i can play L4D2 better and CS:GO better. It can run those games somewhat ok but the choppy edges bothers me sometimes because i have to run them on really low settings.
