I'm trying to run Sid Meier's Pirates! Just got a 6200 GeForce OC 256 MB PCI for my Dimension 3000 desktop, 2.8 GHz Pentium, 512 MB RAM. Card seems to have installed fine, but the game freezes within the first minute of being opened. Usually, Windows then reports that v4_disp.dll got trapped in an infinite loop, although sometimes the game crashes even earlier than that. Un- and reinstalled game. Un- and reinstalled card drivers. Got updated drivers from nvidia -- I looked for 84.21, which I saw recommended in another thread here, but I couldn't find it, so I just took the newest stuff. How can I start trying to track down what the problem is? Are there other graphics-intensive things (other than games) that would provide an adequate challenge? Pirates ran better on the old card, an Intel integrated thing that came with the computer, but by "better" all I mean is that it tended to last longer before crashing.
