lots of (= at least 5...) recent forums post found on google with similar problems. Seems (seem ! nobody know for sure) that the 191.07 driver -may- mess up with some motherboard... But your ASUS P5Q-E does not seem to have the nf200 chipset reported to be affected. http://forums.nvidia.com/index.php?showtopic=110045 for example
It can be many others things,however. Here are a few ideas you may not have tried yet:
-You say there is a multicore rendering option in game ? perhaps start by turning it off. it seem to me the most likely source of problem.
-Or/and try to run the game on a single core. (alt-ctrl-del / task manager / process / right-click, set affinity.) And possibly, forcing Mcafee on another proc
-check if your sound card did not got installed twice. Sound impossible, but i saw it happen once, and it produced freeze and sound loop.
It could be a power supply or overheat problem, but i really doubt it, given that you report everything is working fine. Still, if you have the time, you may perhaps try downloading a benchmark program and stress-testing the stability of your Graphic card under heavy load. Just in case the l4d2 demo is asking too much from your system and push it pass its limit. Wich is unlikely, your hardware is recent enough.
Hope this may help, or if not, that nvidia will answer fast with a solution.
