so this only happens when i play h1z1 it doesnt matter what im doing in the game at one point it will just freeze then my computer will restart. sometimes it lets me know to search for error memory management on google. and more recently i got an error message to google ntsf_file_system. i have tried using windows memory diagnostic with no errors but i never recieve a log upon logging in afterwards. i have also used memtest86+ and passed with no errors as well. i also checked to see if my videocard or motherboard needed driver updates and both are up to date. i have a brand new install of windows 8 and a brand new hdd.
