I recently built a new pc, and got everything up and running with a temporary gpu. I was using a used Asus gtx750. I tried switching out to the new gpu (XFX Radeon RX 580) and the pc won’t boot. The vga light stays on, and occasionally both vga and boot lights stay on. I tried plugging in both GPUs and the system booted. Windows recognized both GPUs, and I swapped HDMI chords and video was coming out of both. I removed and wiped the drivers for the Asus, restarted and once again the system won’t boot. I’m completely lost as to why it works and then stops.

I got it to work in pcie slot 2. Downloaded the drivers and tried switching it to slot 1 and it didn’t work. I know the slot is fine, because the gtx750 worked in it.
