just finished my build and the computer turns on but it doesn’t post and the mb usb doesnt work.

[heavy charm]

i have an asrock b550m itx,5 5600 and a 6700xt with 32 gb 3600mhz cl18 memory, phanteks revolt 650 80+ gold.
i just build it and when i tried plugging it into a tv via hdmi, it didnt post and my keyboard/mouse didnt light up

[cinder wolf]

Is the b550 mbo updated for Ryzen 5000 CPUs

@heavy charm

[heavy charm]

yeah, it says series 5000 ready on the box

[cinder wolf]

The non x 5600 came out 2 years after the 5600x does the box say what 5000 CPUs it's updated for?

[heavy charm]

nope, it just says “AMD RYZEN 5000 DESKTOP READY”

[cinder wolf]

If it says P1.90 means its updated for the Ryzen 5600 and the problem is something other than your bios if it reads P1.10 that means your mbo bios is not updated for it @heavy charm

[heavy charm]

do you know what that is close to on the mb?

[cinder wolf]

Reddit says It's on the back of the wifi module, facing the heatsink.

[heavy charm]

Kinda hard to see it, gimme a few minutes

[heavy charm]

It says p.10

shit

[cinder wolf]

We found the problem the mbo is not updated for your CPU

[heavy charm]

Thanks for the help, I’ll take it to a shop so they can update it

[cinder wolf]

No problem

[heavy charm]

Should I take the whole computer or just the mobo?

[cinder wolf]

Might as well take the whole PC just Incase the problem is more than just the bios

[heavy charm]

Alright, thanks

[cinder wolf]

Wait it says p2.10 that came out after your CPU

[heavy charm]

So it’s not that?

[cinder wolf]

P1.90 is the bios that supports your CPU p2.10 is is a much newer bios so you should be fine,

[heavy charm]

Very well

Then what could the issue be?

It says the version l2.62 supports the 5000 series

The other ones are all g series

@cinder wolf

[cinder wolf]

P1.90 supports the non x 5600 https://www.asrock.com/mb/AMD/B550M-ITXac/index.asp#CPU

[heavy charm]

huh

[cinder wolf]

https://www.asrock.com/mb/AMD/B550M-ITXac/index.us.asp#BIOS and p2.10 is two bios versions newer than p1.90

[heavy charm]

then could the motherboard be broken?

[cinder wolf]

One second wrapping my head around asrocks bios names and what is really supported

Ok the bios is not the problem

[heavy charm]

Damn it

What could it be then?

I’m stuck

[cinder wolf]

Could you send a picture of the PC guts so we can see all the plugs and such

[heavy charm]

yeah lemme just rebuild it again

That’s what I thought it was so I took it all apart

[cinder wolf]

Sorry about that

Maybe rebuilding it will fix it

Make sure all the plugs are full seated in like the massive 24pin and the top left CPU power connector hidden next to your rear io header

[heavy charm]

lol, not ur fault, i had already started taking it apart before you told me about the bios

[cinder wolf]

This sneaky CPU power connector was plugged in right?

[heavy charm]

Yeah it was

[heavy charm]

The only thing that needs to be plugged in from the mobo to the psu are the motherboard connectors and the cpu ones right?

[low wolf]

24 pin and pin to the cpu part on left top

And or some to the gpu if it has any

[heavy charm]

yeah

alright

gimme 20 minutes and I’ll send a pic of how it looks

[low wolf]

After that you can just turn it on with a screwdriver

Shorting out the power pins

[heavy charm]

cpu

can’t really tell but it’s in

It also clicked

@cinder wolf @low wolf

I have these 2 pci e cables, is there a specific order?

[cinder wolf]

Nope

It's best practice to not daisy chain them, meaning only using one cable per socket

But that leads to a messier look

[heavy charm]

I turned it on and still nothing

No usb from the motherboard and no display

[cinder wolf]

The power supply switch is on and the monitor is connected to the graphics card ?

[heavy charm]

It turns on

It just doesn’t have usb from the motherboard and no display

Any clue on what it could be?

the case does have a pci e gen 4 riser cable

But that wouldn’t explain the usb not working

[cinder wolf]

So when you press the power button on your case the power supply fan turns on?

[heavy charm]

Lemme send a pic

[cinder wolf]

Did you try shorting the pins to start the PC ? If that works that means your case power button is broken

[heavy charm]

But the computer turns on, could that still influence it?

[cinder wolf]

Oh nvm then

[heavy charm]

I connected it to pwrbttn and gnd

[cinder wolf]

Is there an easy way to test it without the riser cable?

[heavy charm]

and when I turn off the computer the gpu fans move a bit

[heavy charm]

Easy? Not really but I can do it tomorrow

Would that still influence the usb not working?

It’s 1 am for me

[cinder wolf]

Unplugged the CMOS battery wait a a few seconds then reinstall it, make sure your power supply is unplugged

If that fails go to bed and get some good rest

[heavy charm]

I hate this cmos battery

I’ll do it tomorrow cause I gotta take the radiator off to be able to access it

I’ll let you know

[heavy charm]

Should I also press the power button or something

[cinder wolf]

Alright sorry I couldn't help that much

[heavy charm]

It’s fine

[cinder wolf]

Just turn off the PC and unplug the power supply during the battery operation

[heavy charm]

Just upset that my first build went like this

[heavy charm]

Alright, thanks

[cinder wolf]

My first build went badly too since I plugged in every connector attached to the power supply 😆

[cunning moon]

It also could be a bad connection to the monitor. Is the cable plugged into the gpu?

[heavy charm]

Yep, the cable works and all cause I tested it

[cunning moon]

Huh

[heavy charm]

Still wouldn’t explain the usb ports

[cunning moon]

Maybe try with only stick of ram

[heavy charm]

I’ve tried it with each, on slot A1 and B1

[cunning moon]

Huh

It could also be a bad connection on any of the hardware

Maybe reseat all the connections you can

[heavy charm]

What does the 24 pin power?

Cause if that went bad then maybe it could be causing all of this

[cinder wolf]

The motherboard, and any fans or USB devices you plug in

[heavy charm]

Even the rgb?

[cinder wolf]

Yes

[heavy charm]

If that went bad it wouldn’t even turn on right?

[cinder wolf]

Yup

[heavy charm]

I’m so confused on why the usb isn’t working tho

I’ll go sleep on it

Getting late

I’ll be back tomorrow

Thanks for all of the help

[heavy charm]

That didn’t work, I’m just taking it to the shop

Thanks tho

[deep lantern]

it might be the cpu, i had the same problem once. it was the dumb cpu.

[heavy charm]

ended up taking it to the shop, just hope its not the motherboard

it'll be a huge hassle to replace it

cause ill have to send it to germany, it'll prob take a week or 2 for them to see it and respond

if it does end up being the motherboard ill just send it back and buy this one
https://www.gigabyte.com/Motherboard/B550I-AORUS-PRO-AX-rev-10#kf

[heavy charm]

ohhh, is that why they send 2 of them?

should I do that when I get the pc back?

gpu is a 6700xt

[low wolf]

Yes always connect 2 seperate cables

It’s better

[heavy charm]

Alright

[heavy charm]

@cinder wolf eyy, guess what

turns out the memory was not plugged in right :/
