Steam: Lockup, forced to restart computer

[StatMax]

Yes! Same thing happening to me. It's not predictable, but every 5-10 minutes (usually in battles) the screen starts totally freaking out, images flickering and lights flashing, tearing, all sorts of problems. And then it's a hard crash, can't even Ctrl-Alt-Delete. I even got a blue screen of death once. Have updated drivers, etc., no help. It's a software problem of some kind, and this thread makes me confident I'm not alone.

This is most unfortunate. Seems like a cool game, but it's completely unplayable like this. I purchased off Steam and am using version 1.7 (never had an earlier version, so I have no basis for comparison). If it helps, I'm using 32-bit Vista, nVidia 8600 series card. Please, please fix!
