Neither monitor displaying.

I really need help. I've been having some issues in my games recently, from overwatch, and then it's started to get worse and I'm getting crashes in games like league of legends. I have no warning signs the fps is fine and at the usual numbers, but all of a sudden cuts out with usually the message 'rendering device lost' it got to the point where I had some spare time, so I unplugged everything from my computer, unplugged my gpu and resat my Ram. Just incase it was either of these, when I plugged everything back into my computer after getting dust off fans etc. Neither of my monitors displayed anything.

So I was obviously thinking "got to be my graphics card giving up" the graphics card is only over a year old though so I thought I'd do some more tests. So I unplugged my display port cables, and hooked up a hdmi to my motherboard, and yet again no display. So now I am really stuck as to what is wrong. The computer powers on completely fine, all fans working including the graphics card. The leds inside my computer turn on also. However my led mouse/keyboard do not work. I'm getting really worried that this could be a motherboard issue. Which would cause me some issues, as im not comfortable with water coolers and I have one installed :/ if anyone has any other suggestions please try point me in the right direction.

I've realised after posting I should of posted my specs:
Graphics card: 1060 6gb
Cpu: i7 7700k
Motherboard: b250h Asus board (I'm already aware of the imbalance of the cpu and mobo but I can't change motherboards)
Ram: 8gb corsair
Ssd: 120gb gigabyte
Hdd: 2tb seagate sshd

Okay, after an hour trying to work out what this issue was, it was that I had put the Ram in the separate dual channel (I don't know why this caused the issue but this was definetly it)
