I still think its the bios, the PC doesnt even beep or light red light when no ram is installed, i just dont know how to fix the bios. Already programmed all the bios I could

it same model
 
I assembled two HP Z420 machines. One started without any issues, but I ran into problems with the second one. The motherboard (618263-002) started up for the first time with a v1 processor. I updated the BIOS, replaced the CPU with a v2, and it stopped booting. Nothing helped, including returning to the first v1 CPU the fans just throttling and the screen remained black. I tried emergency recovery with a flash drive, but it didn’t work 8 flashes and 8 beeps appeared at startup.

I created a dump, inserted the padding section into the BIOS 3.96 from the website, but that also didn’t help still 8 flashes and 8 beeps, then 16 flashes and 16 beeps.
