My Pc is stable on all my other games never crashes, it is very unstable with mat_queue_mode but even with out it, it still crashes on startup and in game. Tis annoying
Odd...
What OS are you using?
I'm using vista x64 and I sometimes ( read as, once per 15 hours of playing at most) also get a crash to desktop during play, this happens so rarely I barely care about it though...
My mate on vista32 is complaining about errors and crashes too, especially during map changes for him...
But except for very rare things, I have no real problems with tf2...
Have you tried a different OS to see if it fixes it ?
