Store bought game, problems with words and pictures

Ok I love the game but I am having serious problems, I can play the game for the most part, but I am having a few problems like a black square around the cursor, black squares around the flys, which isn’t that big of a deal, the big problem I have is that every 10 mins or so I lose all the words, I can still click on everything if I know where it is but I can’t see any of it. I am playing full screen and click alt-cont-dlt and it brings up my task manager then click on the tool bar icon and the game is back to normal for another 10 mins or so. Is there a way to fix this? I am guessing its my graphics card which is a NVIDA Gforce 4 MX440 with AGP8X, any other information you need just ask, please help me if it is possible cause I wanna play with out exiting all the time. Thanks.

Hi, this sounds very strongly like a graphics card driver issue. I think your card should be fine running the game. Is this under Windows XP? you probably need to update your drivers:
