I've got a new AMD Sapphire RX 580 8GB. and placed it on PCI 16x on Gigabyte G1.Sniper M5.
I have downloaded RX 500 drivers for Windows 10 64bit and installed that, but it did not detect the GPU.
I can not see the GPU in Device manger under Display adapter either but the blue lights are on while the fans do not rotate.
How can I fix this?
What is the capacity of the PSU in the system ?
Do you have the power connectors attached to the card ?
Does the motherboard have a UEFI compliant BIOS ?
