Well it's kind of useless telling you to check out odd fan noises as soon as they start, but I guess you'll know for next time. Video cards can get extremely hot, so I'd say your problem is there. My bet is the burnt smell is just all the dust on the video card when it overheated. Circuitry tends to deteriorate quickly in heat, even if you don't see a big burnt spot or a popped capacitor. Hopefully nothing else went wrong along with it.
Do you know any good old fashioned geeks who just happen to have a spare video card laying around? (I assume yours is PCI-e) If you can get one, try switching it out. Obviously if this works, that's your problem. If you don't know anyone who hoards electronics, and you're willing to spend a little to figure this out, you could always get a dirt cheap video card on the internet (or buy an upgrade, and justify it like that - but I'd be wary of plugging an expensive card into a suspect mobo). I would expect the card to have died before it damaged the connection to the mobo.
