You might want to try reinstalling. There's an option to expedite the process in the Metro menus, same place as where you set the timezone. I was having strange crashes, and a reset seems to have fixed the problem. I suspect it was an issue with the drivers I chose to install; this time I let it use all the default drivers provided through Windows Update, plus the driver package for my video card, and the crashing seems to have vanished.
