ok i just got a new computer yesterday and it came with a NVIDIA GeForce 7300LE 64MB video card and it has 2 gb ddr 2 ram 400gb hd its an Intel core 2 cpu with 2.13GHz. Well i went and bought Halo 2 for Vista and the graphics are really good and the sound is perfect but the game skips/lags just in the menu then when in a match it plays lke a really bad laggy game but everyone is in the green connection. is this a graphics card problem, should i get a new one??????? some one please help
