Question Help with black screen on new build ?

[jimijefet]

Hello.
Today i got my new mobo, CPU, RAMs and SSD:

Mobo: msi b650 tomahawk
Cpu: Ryzen 7800X3D
Gpu: 3060ti
Rams: gskill trident neo 6000mhz cl30
Psu: 750w chieftronic gold

So i started to install these components. First i did flashback with usb disk 32gb i changed the file name to msi.rom

My psu was connected to mobo. i install bios i think cuz i saw white led and then white led stopped. So after this i added every component and booted my pc. Pc booted but to my monitor i was getting no signal, it was black screen. Then i tried to boot without gpu, didnt work

I tried to boot with only 1 ram it didnt work. From debug i see red and yellow lights (cpu and dram)
At some point i took off cmos battery, waited couple of minutes and then put it back. Didnt work. Now i have taken all the components off. Trying to bios update again with psu and mobo. **** . [Moderator note: removed poorly masked profanity.]

Did you connect all power connections into the power supply as well? there are multiple connectors that have to be connected, not only one or two, but three for the motherboard
MB + MB + CPU

which bios version di you try? version 7D75v17 would be the latest

Did you flashback step by step like this?
