Okay, new update.
I went to control panel >> system >> hardware >> device manager to do some snooping. I went to "Motherboard resources" and it says "No drivers are installed for this device". Does that have anything to do with my issue?
Also, I told my problem to my brother, mentioning the info I just gave you, and he gave me a disk. "NVIDIA nForce 2 Series. Motherboard". I put it in and installed it, but the game still crashed and it still says no drivers are installed...
