Black boxes

[beazil]

I run three monitors playing this game. I sometimes get black boxes all over my two peripheral monitors. This game seems to be the only game I ever see this happen, although I do get similar distortion on some webpages and online vids.

Does anyone have similar experiences? I've tried various driver iterations and versions of the game, deleting/reinstalling, etc. Even a complete wipe of my system does nothing to fix this issue. I know it is not an issue of video card cooling - this does not happen anywhere else, nor does my monitor report higher than normal temps. And no, my system is not overclocked.

I'm running dual 470's in nvidia surround at 5040x1050. I7 3.8Ghz Sandybridge, 8 gigs ram, etc. Win7x64. Every version of nvidia driver in recent memory....

Thanks for any help you can offer.
