Question Computer Monitors Shut off after an hour (or so) of playtime

[beboman]

I have this issue that if i am playing a game of any kind that is full screen that after an hour or so the monitors will shut off. I have updated the graphics card i have updated drivers i have changed the PSU i have changed the monitors and the cables and i have no idea what is happening. Is there a diagnostic tool i could use? Anyone have any ideas? I can provide speccy on request, not sure how to link it here.
