New build, unresponsive after idle over night

[Loco]

First of all, hi. I have been a lurker for a good while. But i finally actually registered.

So I built a new rig about a month ago. It is perfectly stable in use, no problems at all. When I leave it for the night though it either wont turn the monitor back on or is completely unresponsive. Im not sure which.

-here are specs:

Loco, I apologize, our spam filter was a little overzealous and hid your post. I just set it as approved for you now.

You should have some posters helping out shortly! to the forums!

Maybe set your power options to never turn the monitor or off or sleep over night and see if you wake up to any errors. At the very least hopefully you'll be able to better diagnose?

I had low voltages cause a similar problem on a 775 build that was diagnosed and fixed by the fine folks on these forums. Best of luck.
