3 Commando Brigade

Weird crashes

If you're using the most up-to-date version of TeamSpeak, that is your problem. It's not compatible with the ACRE plugin.
If you don't need the newest version of TS for anything else, uninstall it and get an older version.
It is possible to have both an old and new version installed but it's a little more complicated to explain.

TeamSpeak old versions

After doing this you will have lost your 3CB TS badges, so poke an admin from the lobby to get your channel privileges back.

I'm using 3.0.13.1 with no problems.

You're overclocking?
That would have been the first thing I'd suggest switching off! 

Glad to hear it.
Imo from decades of experience (!), over clocking, for the tiny gains in fps achieved, is never ever worth it for the problems it causes with stability, unless perhaps you're water or Peltier cooling.
