Desktop becomes unresponsive after idling for short time.

[quickbeam1213]

So I have a peculiar problem that I'm hoping someone can help me with. I recently built my first gaming computer. Runs great, except for one thing; if it idles too long it becomes completely unresponsive and I have to either hold in the power button or hit the reset button. The screen remains on (it glows) but it is blank. I have the power button set to put it on hibernate when pressed, but when it gets stuck, hibernate won't work so it isn't just the monitor failing to come back on. If I move the mouse or press a button on the keyboard right after the screen goes off it comes right back on. It's only after I've let it go for a little while that it just stops responding. I have no technical data or error messages to give because there are none. Specs are below.

Motherboard: GIGABYTE G1.Sniper H6 LGA 1150 Intel H97

RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL

Graphics Card: EVGA 04G-P4-2983-KR GeForce GTX 980

CPU: Intel Core i5-4690K Devil's Canyon Quad-Core 3.5GHz LGA 1150

I think those are the essential specs for a problem such as this. Let me know if you guys need more.

If you are running windows you can perform a selective startup with msconfig and disable all services to make sure a third party isn't causing the issue.If running it this way corrects the issue then you will have to find the service responsible by running them one by one. You could also make a screen saver but not allow it to sleep under power options.

Have you check your power options,

start > type: power options > change plan settings > change advanced power settings > and check what you have enabled / disabled - it could be most your components are shutting down after you leave it for X minutes.

BTW check your event viewer logs, it might show useful info we can use to get to a solution.

Make sure all drivers are up to date as well (sound, video, chipset, etc.).
