Question PC shuts down

[Rebuke]

Hello, my PC shuts down on specific game (Lost Ark) when I stay in a city even for hours it’s running fine, the second i play a dunegon it suddenly shuts down with no warnings, it used to do it on Throne and Liberty too but after updating the game’s drivers stopped also on The First Descendant too but I didn’t find solution to fix it there so quit. Changed my RAM before playing all of those games before that didn’t have a problem. I’m not sure what causes LostArk to shut down the pc even with lowest graphics on. Any suggestions what I could do?
