hi, I am new to computer building and have just bought a system,

AMD Ryzen 5 2600
ASRock B450-HDV
gigabyte geforce 1060
Cooler Master MWE gold 750w
XPG m.2 2280 128gb PCIe SSD
Seagate 2tb HDD

I cant seem to get the graphic card to power on for longer than 10 seconds or the system to post when the graphics card is in the machine
When I unplug the graphics card it beeps at me 5 times (missing vga card) which is to be expected as AMD doesn't have any onboard graphics.
i am at stumps with an answer and am very confused could someone please provide clarification on what may be going on?
