With a freeze crash there is a possibility that there isn't much, unfortunately this time the case.
In the Windows Error Reporting logs, most occuring was Steam Web Helper executable crashing.
I don't assume there is an update for Steam, so my suggestion would be to either reinstall or remove it for testing purpose.
