Can I ask which graphics card it is?
You need the drivers for the hardware for it to run, have you double checked the graphics card is the one you've plugged into your monitor? A lot of the time people will install a graphics card and plug their monitor into the on board slot.
If all of this doesn't work, it may just be they're not compatible, a lot of the time certain hardware won't work with XP because it's not supported by anything anymore.
The problem now with Windows XP is that is no longer supported by Microsoft. So XP reached the end of it's useful life. If I was you, I would upgrade to at least Windows 7. That way at least Windows 7 can load the native drivers if you don't have the CD's with the divers. Unless you have the original CD's with the drivers, you will always have issues with Windows XP. I hope this helps.
Really first you need to identify the series of the graphics card .So you can run CPUZ it's a small program that will tell you all about your computer hardware . Should be easy to find just google the name . Once you find out the series of the card or chip then go to Nvidia to search the chip or card # and see if there are XP drivers available . The only other thing you can try is an all in one driver disk. Called Driver Pack Solution it may find a suitable driver. Herman
What operating system are you using? Have you checked the system requirements for this game? It appears as though you need a processor that clocks out at 1.7GHz minimum, but the recommended is 2.4GHz. This may have something to do with your issue, since it appears that the processor you listed does not meet these requirements. Please, correct me if I am wrong. I don't really know the full story here...
