i think I would try a fresh install of cod, then uo before the f word lol. Before you do that, you should check your main in uo and make sure you do not have any custom configs that alot of asses make you dl to play thier mods. A good indication that this has happened is your consol screen has been taken over by someone's idea of what it should be.
Check for that madness before deleting or formating. The hardware you have is goood enough to run uo.
Another thing I am concerned about is 1.5 gigs of ram. Sounds like you are stacking ram meaning your motherboard may be mad at you. Some motherboards hate that and some even go as far as not even recognizing the combination.
In short, check your specs on your MB and also make sure your ram is the same type, speed and channel.
if all else fails...then reload game and stay away from teh gay mods.
