[SOLVED] PC died overnight no signs of life

My computer was working completely fine last night nothing out of the ordinary. When I woke up today I tried to turn it on and it wouldn't boot. I tried just about everything from the power switch on the back to unplugging everything and plugging it back in. I borrowed a PSU tester from a friend and tested it out and it shows my PSU is fine which is quite worrying. On the motherboard normally there is an idle light for power and it is not lit up. I have had to RMA my board twice so honestly, I wouldn't be surprised if its that but I wanted to see if anybody had any other ideas before I have to set out a few hundred bucks for a new board.

Motherboard- ASUS ROG Maximus VIII Hero
Processor- Intel Core i7 6700K
PSU- Corsair CX750M
Memory- Corsair Vengeance LPX 16GB
GPU- Gigabyte GeForce GTX 970 Windforce

Most likely the board again , I had the same one die on me.

Ramdom and weird update. The power LEDs on the board have come back on completely randomly as in I did literally nothing and I just noticed they were back on, however the PC still will not boot. Still looking like a motherboard problem?
