I installed windows 8 today and it has crashed/hanged several times today while surfing the internet. just hangs no error message and I have to press the power button to turn it off.

all the drivers where included with the windows 8 installation but I installed the latest NVidia driver. tried 320 and the beta 326 and the same thing happens.

I have tried different browsers also firefox and IE10.

use AVG free AV.

any ideas.
