6 days trouble free. switched on this morning and get a blue screen with the message "whatchdog initialisation" it would appear this is a well known problem, but so far no definite reason for the problem (possibly Nvidia GPU) Eventually restarted with a new desktop, but numerous problems. all my folders on desktop have gone and Apps on the taskbar have dissapeared. bulid 10586.
The blue screen was at start-up, so Avg was not running. Win 10 is up and running OK, but almost as a new installation. All my Apps are still available, but have been reset as though they are new installations. Scouring the web does not bring up an answer to this problem, but in most cases I've read about it would appear to be down to be a problem with graphics and mainly users with dual monitors
