Question GPU gives no signal output ?

[xXMatr]

Recently my gpu just stopped outputting any display, I had a spare gpu laying around so I decided to test the system and it worked so I concluded it is the gpu.

The gpu turns on completely, fans spinning, lights on and so on.
I tried all the gpu ports and different monitors.
The gpu is a MSI 1060 6gb

As for your method of ruling out your GPU being the issue, please state everything you've done that have been unfruitful. Might want to also include the make and model of the spare GPU as well as the age of the PSU.
