Computer falls asleep whilst playing certain games?

[Mr Arky]

ON MY OLD PC (Current), whilst I get my new one sorted out, I've had this ongoing problem which one day just started happening out of nowhere and its so annoying its unbelievable.

More than half of the games I go on after about 10 mins my computer says, monitor going to sleep, then I have to restart the whole computer.

I have tried many solutions such as,

Changing my computers power plan.

Turning both sleep and hypernate modes to never.

Uninstalling and then reinstalling the display adapter in device manager.

Making sure everything is up to date. ie checking for updates.

Lowering the graphics settings even when they would run fine otherwise.



Any help would be of great assistance, thanks.

Might it be the PSU?

Does your monitor have any screen settings, which may be causing this.

I've turned all the sleep mode settings off for the monitor, other than that I'm not sure where to look or what else there could be.

Also when I go on device manager, under monitor, it comes up with 2 of the same thing? even though I have just 1 monitor, idk if that helps or not.
