Hi there. Its my second time to build PC but this time I use intel set instead of AMD.

MB: Asrock Z390 Phantom gaming DLI/ac
Proc: intel i5-9600KF (With mastercooler Watercooling system)
Ram: Gskills 16gb 4266
Gpu:RX 580
Storage: 240gb Adata SSD
PSU: 700w

after installing everything, tried to power up the PC. Motherboard gives 3 blinking red light, Cpu cooler running GPU turning but the radiator fan at the back is not and there is no display. Cant even get the motherboard to post and cant enter the bios. Can someone help pls

9600KF need bios P1.20 or higher

monitor connect to the gpu?
On the bios portion on the motherboard it says P4.30. Plus on the box it says 8th and 9th gen supported.
update: Tried both GPU and Motherboard HDMI connector still no Go.
next I tried was to manually and one by checked everything. Tried running MB + Proc + 1 Ram on channel 1 then PSU and still same result. tried cycling on all RAM slot and still the same. One thing I noticed the LED on my RAM not glowing plus the radiator fan at the back of the PC is not working as well. Only the CPU fan is ON and running plus the red lights glowing on the motherboard
