X1300/Game problem

I was having the same problem that craig7368 was having with my SiS mobos....Instead of doing what he did I went out and purchased a Radeon X1300 AGP card.....I updated the software(game) and tried to run it.....It loads as if it was going to work but nothing shows up......You do see briefly the desk top flash like another window is going to open but doesn't......The cursor will then disappear and not come back but in the task bar a window icon appears but it does nothing when I try to click on it before the cursor disappears........I end up having to ctrl alt del it and then the cursor shows back up on the desktop.......My system is a 2.4 ghz Pent. w/1 gig ram etc.......Any help would be appreciated......thx....
