New pc not booting

[Hermaszewski]

I have Just finished my build, however when I Press power button nothing happens. No fans spinning, no sound, no reaction. I tried reaseting all of the cables but nothing seems to work. My cpu is ryzen 5600, moyherboard Asus tuf b550 and gpu is 6750xt.

is the PSU on? Do some LEDs on the mainboard light up?

Power switch cable is plugged to the proper power switch pins on the motherboard?

Psu is on, i can see some RGB light on motherboard, and I can see  flbk_led1 that is flashing

But my motherboard had ryzen 5000 Series ready on package so I am assuming bios update is not needed

the 5600 came out later you need to update the bios

Are you sure that i need to update it? From what i read sticker ryzen 5000 Series ready means that it should work without bios updating

That my best guess, the 5600 came out month after the first Ryzen 5000 CPUs so the Mainboard can be Ryzen 5000 ready without supporting the 5600 out of the box... i dont in the past you could see a date of manufacturing on the mainboard in form of a date code, if there is one you can check and see if the 5600 was a thing at that time... but i would just use BIOS-Flashback to update the BIOS...

Manufacuring date is 2022. 08 so it should work.

The 5600 and 5500 came out later and need a newer BIOS version than for example the 5600X which was released earlier

gues it should but its still my best bet, especially because the bios Flashback LED is blinking maybe ist just a signal that a BIOS update is needed

have you tried resetting the cmos?

So after spending some time i solved it. I assembler pc again from start, update bios, and it seems that one stick of my ram was faulty. While running only one stick everything works now.
