Screens turn off, inputs do nothing, but can still hear music from my computer

[Jensen_4]

So, randomly when I'm on my computer, my screens will turn off (moving mouse or hitting keyboard buttons does not help), and my inputs do nothing. If I'm in a league game i don't get the sounds from using my spells however I can still hear my music running from I-Tunes. I have tried unplugging monitors and plugging them back in but it doesn't do anything.

Specs:
Windows 10 Education 64-bit
Intel Core i7 4790 @ 3.60GHz
8.00GB Single-Channel DDR3 @ 799MHz (11-11-11-28)
MSI Z97 PC Mate(MS-7850)
4095MB NVIDIA GeForce GTX 1070
465GB Western Digital WDC WDS500G1B0A-00H9H0 (SSD)

Any help is appreciated, thank you!!

What power supply do you have?

Does it only turn off screen? when you say your inputs do nothing, does that mean USB are on or off? or that it just doesn't turn screen back on?

can you tell if GPU is on? I expect you would need to look at fans inside PC to tell.

Try plugging the VGA cable from the monitor directly into the VGA port on the motherboard. Post the results.

Good Luck. Peace.
