Strange PC booting issue

[ukah123]

Hi!

 

I run into a strange issue. One day I tried to turn on my PC and it didn't post(black screen). After  many troubleshooting steps, I managed to enter windows using motherboard GPU.

 

I setup bios so it always boots with motherboard gpu and I've noticed that each time i get to windows my GTX 1070 loads with system error 43 inside the device manager.

 

Interestingly enough, all I have to do to get it running, is disable and enable it, then it loads without any errors and I can run it.

 

This happens each time I power on PC, I basically cannot boot the 1070 on PC startup, have to use moba gpu.

 

I tried almost everything and the last resort I haven't tried is updating gpu/motherboard bios.

 

Specs:

EVGA 1070 FTW Black

Motherboard Gigabyte GA-78LMT-USB3 rev.5

PSU corsair RM650x W

16gb ram
