SOLUTION: Change the microswitch on the GPU card from gaming mode to compute mode
Hi everyone
I've just built a new machine using this spec:
https://uk.pcpartpicker.com/list/YB3QvW
The system was working using the integrated GPU, but I decided to install a dedicated GPU so bought a Sapphire Radeon RX 580 8 GB PULSE. The problem is that the machine will not POST with the Sapphire in a PCIe slot. If I remove it then the machine will POST again. I get a solid red VGA LED on the motherboard. I have tried resetting the CMOS, specifically setting the BIOS to use the PCIe interface as the default output (rather than on auto), and disabling the iGPU. The power cable is connected to the GPU.
Any advice would be greatly appreciated.
Thanks in advance
