COD4 compatibility

I bought call of duty 4 a while back for pc, and installed it, but my video card is totally s***ty...its like some intel bull crap that came with my 5 or 6 year old pc...the age also means that i cant upgrade the vid card. new vid cards fit in pci-express slots, and my pc is pci-standard...basically i fu**** up there.

the game does not work obviously, it just says the video card isnt compatible with some file or another...

I dont want to go out and buy a new computer, and i was wondering if anyone out there knows a way to play it as my s***ty pc is...

i dont think there is a way, but i dont want to have wasted $50...

any help is greatly appreciated...
