If "every" game you've bought on Steam crashes - which I doubt - then that's your computer, not Steam.
Most of the complaints and problems I have to deal with on a daily basis are down to user error, yet what's the most common thing I hear? "The computer's broken" or "This software doesn't work properly."
I'm not saying Steam doesn't have its problems, but your issue is far from Steam related.
