-a watchdog error indicates that a driver/hardware took too long to respond.

It can be caused by several issues so I would start by going to your motherboard vendor site and update the various drivers for your mother board.
Also, if you have a solid state drive be sure you check for firmware updates. lots of the older drives have firmware bugs where the drive ends up getting behind on it internal cleanup calls and makes the device take too long to respond to windows.
In this case, you would want to clean up your hard drive by deleting the internet cache files, old memory dumps and programs you don't use.
and make sure you have plenty of free space on the drive (20% should be fine) empty the recycle bin, and reboot and go into BIOS and let the machine go idle over night. After 5 mins the Solid state drive will start its internal clean up routines. They will run much faster if the files are not in use by windows, or the windows does not tell the system to put the drive to sleep after 20 mins.

anyway, do that and if there is a firmware update apply it after the drive has completed its cleanup (sat full power in BIOS for a few hours)

-There are other conditions that will also cause the same error, UBS devices tend to cause a lot of the problems. The driver hangs during the install, while some software is running waiting for the driver install to complete. These take more effort to fix, generally you have to do a BIOS update, then a chipset driver update, and maybe a USB 3.0 chipset driver update. Then a update for the usb device driver for the USB device that failed to install correctly.
(most often caused by a certain brand of USB wireless ethernet devices)
