meh they haven't fixed the blue screen of death I have been getting since the patch. Nor have they given my spy a knife that can be thrown and does 125+ damage if you get a direct hit.
oh well, life sucks. Bring on Team Fortress 3
User-level software, like tf2, can not cause bsod. You have either fucked up driver or hardware. What stopcode is the bsod reporting? Also write down everything it says so if it's driver you know which one to blame and update. If you are getting something about memory, IRQL_NOT_... etc, burn a
memtest and let it run for few hours, you might have damaged ram module.
