Computer problem or game?

i have a windows xp, and just yesterday i tried to install a game, backyard baseball 2009.....the game installed, everything was good, than when i clicked to play it there is no mouse on the screen, nothing is moving, and it is like slo-mo...there is no way to play it now. is it a problem with my pc or is it just the game? other games seen to work normally, backyard baseball 2005, hockey 2005, madden 06, 07, except this one....is it the game or is my pc getting old for such new games?
