I recently acquired an RX 580 card and installed it into my computer.

When I turn the computer on, with the GPU installed and powered up I get the following:

A black monitor that seems to be receiving no signal

A GPU that is at least spinning.

I cannot access Windows 10 when the GPU is installed. It appears as though the mobo is prioritising the GPU, but it wont send a signal out. To access Windows I need to remove power to the GPU and connect to my monitor via the on board graphics card


Here is a list of troubleshooting I have already undertaken:

1. Removed all old drivers for old card

2. Disabled the integrated graphics from Device Manager

3. Tried both PCI slots on the motherboard (z77H-udh3)

   a. To ensure my PCI slots are working I tried a friends GPU. It booted fine

   b. To ensure my new GPU is working I tried my GPU in said friends system. It booted fine

4. Installed a new 750W gold rated PSU

5. In the BIOS ensured that the PEG was proritised for booting

6. Attempted to boot in safe mode. Transitioning from onboard graphics to GPU during the power down stage

7. Attemped to pre-install drivers for the card. But AMD tech says, due to the card not being powered up (in order to access Windows) that it cannot find any new hardware


My last idea will be to flash my BIOS, but I thought it was smarter to put it out here before i take this action
