Question Switch from nvidia card to amd card

[Frankoli]

I receive my new msi rx570 8gb armor edition try to install it on my p9x79 deluxe I7 3820, 8gb ddr3 patriot viper x division2 1866mhz, psu ocz 800w.I desinstall the nvidia driver than my old zotac gtx 580 amp with 8 and 6 pin from the psu the rx only have 8 pin.I turn on my pc than the vga light turn on with 1 long beep and 3 short.So nothing come from bot hdmi or vga port and my mothe board don't have any port. It 's that something wrong I'v been doing or I'm missing some step because i don't see anything in the instruction of the card about reboooting the bios and went I put back my gtx everything is work fine

Make sure your GPU is properly connected in the PCIe slot and to the PSU.
Ensure your bios is up to date.
Following that I would RMA the GPU.

VGA Light and VGA beep code on a new GPU would usually indicate a GPU that was DOA.
