I'm sorry if this is the wrong place to put this but I didn't know where else to post it.
Just today I've been having problems with TF2 crashing after around 15 minutes of play. Everytime it's either the same error or on occasion a blue screen which needs a hard restart. Here is a screenshot of the error message:
The bluescreen error I got was IRQL_NOT_LESS_OR_EQUAL.
This all just started today. The last time I played (at the weekend) it was fine. The only thing that's changed since then is that I installed Red Alert 3 but I can't see how that would have affected it. I've updated my graphics drivers (4870) from 9.4 to 9.5 but it made no difference. Have Valve released any small updates since the weekend? It's the only other thing I can think of.
