It could be a number of things like over heating.
I have searched google to find out for you and someone said go into Steam's options, and disable the in-game overlay hope it works for you try pasting your question in google to see if there is a solution for you.

Sorry to hear you are having issues with trying to load/play the game. But as Nolly mentioned it could be a number of things. So lets try to eliminate some possible causes and hopefully fix your issue.
First, What windows version are you using, what video card do you have, and what drivers are you running? And are you running WHQL drivers or beta drivers?
I know you mentioned you updated your drivers, but sadly this could be a possible cause. Something may have corrupted upon installing, or you may have not removed your old drivers properly causes conflicts.
Have you made any notable changes to your computer(Hardware or Software)? Software end will mostly be drivers and stuff, but hardware such as upgrading cpu, ram, fans or anything really. If you did make hardware changes make sure everything is connected and running properly. As nolly stated most newer mobos will automatically shut down due to heat.
Now can you play any other games through steam? Can you play any games without steam?
This should be a good start. If the problem i'snt resolved theres a few more things you can try.

Depending on your rig, try updating your BIOS, if you don't know what your Mobo make is use something like Sandralite to find out, there are known problems with nvidia / amd setups that need a bios update.
