I have a similar problem.... it doesn't get to any screen but my computer reboots. Also have this problem on Farcry, when I die my computer reboots. (Kinda ironic, but annoying!)
Guess what.... I have an nVidia GeForce 6200 too (128mb model).
Is there any definate way of fixing this yet? Or would I be better just getting a new graphics card?
edit: Meh, went back to my trusty ATI Radeon 9600 ^_^ Works perfectly now. Anyone asks me why I don't like nVidia.... this is why.
ATI rock!
