Hi, the Crash is basically your out of memory. How much ram do you have ? Reboot the computer often to free up ram. Suggest remove all programs that do not need to start up when you start the computer. Go through Windows 10 start button and right click every thing there to see if can uninstall it. Get rid of Tiles if your using them as they take massive amounts of Ram and bandwidth. Go through Settings, every single category and delete what can be deleted, uninstall what can be, turn off everything you do not use or turn off things that startup when computer starts. Get rid of almost everything you can. Buy more Ram if can do that.
