Process is running but nothing comes up on my screen or task bar

I seem to have a problem with programs acting like they are going to start, then I get nothing. say I want to play Warhammer 40k for instance, steam tells me its preparing it to launch but nothing happens, the window with the launch notification goes away but the game does not show on my screen nor my task bar, But if I bring the task manager up and go to processes it shows the games process is running.
But a game like Metro 2033 will run just fine.

My computer is fully updated (drivers as well)
windows 7 64 bit
Ive checked compatibility

Any help would be greatly appreciated
:)

Thanks :)
Im assuming I am not running comodo seeing as how I do not know what it does D:
the resolution depends though, my computer usually runs at 1366x768
the games vary on how well they perform, I have to run Metro at 800X600...

Thanks! while this tool is useful there seems to be a problem with it. According to this tool I do not even meet the minimum requirements on any game listed, I even went to a much older game, Halo 1

and the results I got was this:
