Locking up on TF2

[Makaze]

Running into a weird problem as of late TF2 wise. Sometimes during play, the game will lock up as akin to a man who's eaten nothing but Velveeta for a few weeks, it doesn't seem to do this on a stock map server, or with other games, Just TFP(Mainly server 5 and 2) any suggestions or guesses as to what the culprit might be?

I've hit the steam boards, run defrag and all that good stuff, and I'm sort of running out of options. So any insight you admin types or computer saavy go getters might have would be very appreciated.

What sort of lockup?

Occasionally in TF2, my game'll go HURRR for a second, things'll skip around, and usually when it 'unlocks', I'm dead.

I've only had this happen on TFP, but then, it also doesn't happen very often, and I usually don't spend long on other servers, because dominating pubs as pistolero spy or battle medic gets old. Quick.
