Im running, Windows XP Pro, with an nVidia Nforce motherboad with graphics and sound all on board. And I have an Athlon XP 1800+ Processor, and i have a stick of 256 ddr.
When i play MOHAA the game runs fine, but randomly during play drops out to windows. The game does not freeze or crash the PC just drops away to windows. When i try to run the game it realises it has crashed and offers me to load it in safe mode.
Only prob i thought it might be is the memory sharing between the motherboard and graphics card, as it is all on board?
Cheers.

try upgrading your video drivers

as my motherboard has everything on board nVidia do an all in one driver. And i have updated this already

I've the same problem. I run under AMD Athlon 2200+ and ATI Radeon 9600. I have also uninstalled the game and updated to the latest drivers/version. Can anybody help me? You'll find more system specs at "Medal of Honor Allied Assault crash problems" topic. Hope it helps...
