Hi, I’m 15 just finished my build, I have turned my pc on and there is a long beep lasting around 7 seconds with a gap of 4 seconds in between and the yellow boot light is on on my motherboard, I haven’t posted yet and would really appreciate some help, my specs are

ASUS Z390-h motherboard
I5 9600k
Strix vega 64
Cooler master ml240
16gb ddr4 gskill tridejt memory at 3000mhz

Don’t need to mention storag

I don’t think it’s from the motherboard I think it’s from the built in hue light strip in the h500i and the cpu I got today and the motherboard hasn’t been opened. I think the issue is the boot light which is on how do I solve that
