PC Hangs playing Roblox?

My PC gets stuck very often when I play roblox but GTA, Fortnite, Black Ops 4, Rainbow and everything is liquid on Full HD have a GTX 1070 but when I play roblox my pc stays up again and again for so 2-4 seconds it freezes and if I shut it down by shutting down the button drives only after 20 seconds or so down or just when I drove him up [Windows 10] was only this logging image because there was no name no garnix there was only the image for 15 seconds (That has never happened before, only recently has it happened)
