Is my GPU or PSU failing?

[SUS]

Hello everyone,
I've had this computer for about a year and a half and it's been running fine since i bought it, but about two month ago, my computer started to crash and restart randomly (Both when I was playing games and even when idle.) At first I thought they where just minor crashes and wasn't worried about them.
But the crashes got more and more frequent, sometimes the system would fail to start.
At that point I started looking for possible causes, I checked the temperatures and everything seemed fine.
One day the PC just stopped working completely, with all the lights turning on and the fans spinning at their maximum speed, while the monitor didn't display anything other than the usual 'no input detected'.
I then realized that my GPU wasn't turning on, so I took it off and connected the screen to my motherboard output, restarted my pc and everything was working fine. The only thing that could be failing was my GPU, but to my surprise, after plugging it back it all started working again for about a month, until yesterday, when I started experiencing the same issues again, but this time i haven't been able to get my GPU working at all.
Right now, when I turn my pc on, the gpu fans start spinning for about two seconds before turning off and switching the display output to the motherboard.
The thing is that altought I was pretty certain about my gpu being the cause of my problems, all the sudden crashes and restarts seem to be a PSU issue, and I woul like to know wich part should I replace.
(Hopefully the PSU!)

Specs:
Cpu Intel core i5-6500
Gpu Gtx 1060 6Gb
Motherboard Gigabyte GA-H110M-DS2
Psu Enermax PSU 500W NAXN
Ram 8Gb ddr4

Hate to say it, but it could be both. It's even possible that your PSU has damaged the GPU. Cheaper PSUs rarely have adequate safeties, when they fail they can wreak havoc.

Let's start with the basics. What kind of PC is this, and what are the specs?

If you could post your specs it would help, especially the psu make and model.

I've added them into the post

I would start out with the PSU, they go bad often and they can usually be found at a Best Buy and returned if it isn't the problem.
But yes, it could definitely be the GPU also. You won't really know without a little trial and error.
Definitely go with a good brand PSU though.

Your psu is the worst part of your system. It's low quality and unreliable. So I would say it's most likely culprit.

The psu looks as if it is tier 5 on the psu tier list. This means replace it with a tier 1 or 2.

If you can get the model number, this chart would give more info. It's not essential as replacement is recommended anyway.
