BSOD while playing R6 Vegas 2

[Cool Joe]

When I play Rainbow Six: Vegas 2, after a few minutes, I get a BSOD and the PC restarts. This happens only with this game; all other games work fine. Any idea why this happens and how I can solve the prob?

Configuration details? Any patches/update applies? Happens only with this game or others as well?

I've got an Athlon 3000+ @ 1.95 Ghz with a gig of DDR RAM and a 6600GT. All this meets the bare minimum required to run this game.
I haven't applied any patch.
And I've already mentioned, it doesn't happen with any other game.
