770 refuses to start any apps
 

A weird thing happened to my 770. One evening it worked fine, reboots and everything. The next morning when I tried use it, it wouldn't start any applications or connect to the net. It would show the starting screen in the corner for a while but eventually nothing would happen. The power button didn't work either. The tablet rebooted fine but rebooting didn't fix the problem. After flashing everything seems to work again. I wonder what happened. Has anyone else experienced this?
