New GPU, no display and fans turn off a few seconds after boot

[portharbourbay]

Before anyone says it, the hdmi is plugged into the gpu, not the mobo.

Last week my computer overheated, turned off, and wouldn't turn back on again. I worked out that it was my gpu that was broken as I was able to boot up the pc with on board graphics.

I got my new gpu today (GTX 1060), but when I boot up there is no display and the fans on the gpu only run for about 30 seconds before turning off. I have a 500w power supply which should be sufficient, so I am completely stumped as to what could be causing this problem.

Specs:
i5-6600k
EVGA GTX 1060
h110m pro-vh mobo
8gb ddr4 RAM

This is causing me a tremendous headache and any help would be hugely appreciated!

When you say the PC overheated, could it be that the CPU overheated and is damaged?

It's possible, but not being able to boot with the old gpu and then being able to boot with on board graphics tells me that its the gpu thats the problem

Testing the GPU (or GPUs) on another system will help confirm whether it is as you say or it's the PSU failing.
