My brother has 1.7 ghz dual core processor, 2 gigs of ram, and a nvidia Geforce 6100, as well as 32 bit vista. Now when he sins alone there are no problems, but when we play a lan game, Every so often the game just freezes for anywhere between 30 seconds and 5 minutes. This has never happened in any other game on his computer (even ones that are harder to run), and It seems like a connection problem but that doesnt make sense to me as he uses a wireless connection. Anyone have any idea whats wrong? Thank you
