Well if he is using Window 7 32 bit O/S, he may just need to set the equivalent to the /3GB switch, which is similar to Vista's commandbcdedit /set IncreaseUserVa 3072This must be run as administrator Also depending on the size of the video card he should set it to something more like 2816 (for a 512KB card) or 2560 for a larger size card.
