Setup new rig but there is no video output

[blg42598]

I get a video output with on board graphics with no cards connected. But when I add the cards there is no output anywhere. Not from onboard or video cards. I am using Windows 10 with 5x Sapphire RX 480s. I installed the amd driver without the cards connected to the motherboard. Please help thanks.

Uninstall amd driver.

Reinstall driver with AMD cards connected to motherboard ( i would personally install one board with drivers. restart with the rest connected and your computer will auto find them and install with drivers)

Thanks, i got it. But now the system crashes after a few minutes of mining using claymore.
