Question Black Screens, Error 43 on GPU and Please connect PCI E cables message when booting

[Etienne.]

Hello,

So I started having having problems with my pc for some weeks now and it's behaviour is quite strange, so what happens is that it works fine the first time I turn it on per day and then after sometime my pc black screens ( I can still hear sound and I hear the windows sound of something being connected) then when I turn it on again i get the message "please power down and connect the pcie power cable for this graphics card" and after restarting my pc repeatedly it sometimes boots but I get error 43 on device manager.

I have tried everything reinstalling drivers with DDU checking my temps and a lot of other stuff I found on the internet.

I just want to know if there is someway to repair whatever is malfunctioning on my pc or if I should replace something (I'm thinking it may be the gpu or the psu).

Thanks in advance.

Btw these are my specs:

GPU : EVGA GTX 970
CPU : Intel i7-7700
PSU : Cougar VTE 600w 80 Plus Bronze
RAM : Corsair Vengeance DDR4 8 Gb x2
MOBO : Gigabyte H270-Gaming 3

I've done that multiple times and my gpu needs both of my 6 pin pcie. Thank you anyways
