Screen Stays Black After Idling Until Forced Restart

[Jonathan Nguyen]

Graphics: AMD Radeon R7 260x
CPU: I7 4790

Not sure my RAM brand, etc. would be much more helpful here.

Overview: If left idle (I've actually never seen it go from a live screen to a black screen. Always happens when I'm away), the screen goes black. Stays black until I shut it off. I also notice fan speeds are running pretty high.

Interim Solution: All I can do is hold power on my PC and shut it off and then boot it back on. Doing so brings the monitor back on and fan speeds are back low.

Any ideas? My GPU is updated, along with the mobo, which is an Asus Z87A Pro.

Is this a new issue or was it like that from the beginning? What's your PSU? Is it haswell ready?

Sometimes this is caused by a driver or a bad configuration.

1)Try to clear the CMOS.
2)The UEFI/BIOS has some CPU power management settings including the various C-states options. Try to test with those settings on and off.
3)Check the windows power management settings and test with the 3 available main power settings.
4)If nothing of the above works then you should try to reinstall windows. Sometimes it's the only way to fix various strange OS issues like this.

However it could also be power related (PSU) or hardware (GPU/mobo).

1)Try to test your system with another PSU
2)Try to remove the graphics card and use the internal GPU. If this fixes the issue then the motherboard is fine and the graphics card may be failing. If not it's the other way around.

Good luck.
