I installed an RX 580 8GB graphics card on an Intel DB85FL motherboard, the graphics card is powered by a 6+8 pin connector. Power supply is Be Quit 630 w, RAM 16GB, 500GB SSD+500GB HDD storage, processor i5-4570. Every time I turn on the computer I hear 4 beeps, and after that Windows 11 starts normally, I just have to wait for those 4 beeps to pass. The service center told me that the beeps are due to the incompatibility of the graphics card and the motherboard, and that nothing is wrong.
