Half-life uplink demo... installs fine... doesn't launch.
Tribes (full game)... installs fine... I hear the sound test and all the files are installed... then it freezes.
Launch a cs, tfc, hl game off of steam... all of them look like they're about to load because I get the "preparing to play counter-strike...", then it dissapears and nothing.
Are you using an nvidia card, or an ati card?
I ran half-life uplink demo in debug mode and there's a tonne of the following entries (and of course it never launches):
