alright well while playing cod4 the game will sometimes freeze. wat i mean by this is the game will just freeze up and stay on a frame until i alt tab out of it and come back in. the obvious assumption is that this is from the video card, and it probably is. but, im wondering if its possible that it could be something else? could it be ram, processor, or hard drive? and if it could be one of, could someone reccomend a program to test these with. thank you in advance.
