Question Need advice for weird problem when launching a game

[Dreadbeard]

Hello I need some help, if I leave my pc running for a while eventually for some reason when launching a game the game just hangs and fails to load up requiring it to be force shut with task manager, at which point I try restarting the pc but it hangs at restarting screen and requires hard shutdown via power button ?

A game, so only one game has this issue? Has it ever worked? Everything else works fine? Anything overclocked? Try re-installing this game?
