No Display Signal After Installing GTX 1080

[jerryl3698]

I have a built system that works fine right now:

• 
  Ryzen 5 2400g
  ASRock AB350M Pro 4
  EVGA 650W Gold PSU

I bought and tried to add this 1080 today (EVGA 1080 Hybrid Cooling)

The computer works fine when I disconnect the GPU, but when I try to plug it in, the computer no longer puts out a display signal (Through the GPU or the MoBo). All the fans spin and the lights turn on, and it stays on, until I turn it off again. There's no status LEDs or beeping from the motherboard, so idk what's wrong. The only thing I found was that when I plugged the GPU without power, it pushed display signal and told me to 'plug in power for GPU and reboot.' I checked the motherboard BIOS and its up to date. I built this computer about a month ago, so nothing old, I am just trying to add this graphics card to it. pls halp 🙁


*fixed*

have you tried different outputs on GPU or a different monitor cable?

make sure the eps power cable for the mb is connected. in the bios look for primary display if it set to auto set it to peg/pci. the nturn on multi monitor support so both the onboard and gpu will come on.

After some more fiddling managed to get the computer up and running again, still not sure what the problem was, but thanks for the answers guys~
