Hi all, I recently upgraded my PC's RAM, CPU and MOBO. However, upon reconnecting all the wiring, and plugging it in, a white light is shown on my MSI B550m Mobo. It is labelled "CPU". However, the CPU was unboxed today, and no pins are bent or missing. I then tried it with another CPU, and it was the same. My GPU and RAM isn't the issue because i switched those out too. The Mobo is new too, so Im perplexed. Any Ideas at to what's causing the light?

#

PC doesn't work. Help Please!!!

White usualy means its posted or doing ram check at least on asus boards. Weird tho
I had issue when I bought completely new parts new mobo all new put it in together properly and finded out that the motherboard is dead frrom the start

#

Fans spinning no sign of posting nothing means the Motherboard is dead probably.

#

Have you tried to swap out monitor?

#

Disconnect GPU and plugging your monitor into motherboard

#

Running motherboard without RAM.
Than with 1 stick plugged in only.
Than with all but CPU in it it should display no CPU found that means the motherboard is ok
If nothing at all even after trouble shooting the basics and swapping parts and all doesnt work,
Might be a power supply or Motherboard failiure.

#

i have tried plugging it in directly to my Mobo, but that produces no results either.

#

Unfortunately. I had the same issue and could only return my motherboard to the seller and ask for a new one.

#

and it was working after that

#

if you are not able to get into bios, the motherboard is bricked by some reason

#

Cuz usualy it can diagnose itself like no RAM detected. Or no CPU or no Boot drive or no input

#

if absolutely nothing, its most likely dead

#

and in fact after returning they figured out it was a factory defect and I got a full refund

#

it happened on msi board

#

Also I hope the picture of your ram is just a try out and not for reals

#

#

This is the correct way to install it xD

#

But assuming all your other components are fine. It sometimes happens with motherboards. You will not be the first or the last one its a pretty complex sothering masterpiece. Something can go wrong sometimes

inner hollow Jan 21, 2023, 1:13 PM

#

alright broski ill try to get it refunded

#

thanks

halcyon bone Jan 21, 2023, 1:13 PM

#

Does the light say CPU tho

#

Cuz all I can find on the internet regarding this is that the GPU is not detected

#

or CPU has bent pins

#

which you said is not a case

#

Try unplugging your gpu for a sec and flash the BIOS if you have Flash bios button somewhere in the back or on the motherboard

#

than restart, reseat it and try again

#

Seems right. Idk, check this post if you havent before refunding

Here in this article we will provide you a detailed guide on the Asus Motherboard White Light.

#

but I guess if nothing works can be fault at motherboard, not detecting stuff and reporting faulty things. also make sure thru PC part picker if the components you are using are compatible with your motherboard

inner hollow Jan 21, 2023, 1:19 PM

#

#

No bent pins

halcyon bone Jan 21, 2023, 1:19 PM

#

Interesting ...

#

Problem is when motherboard fails its so hard to detect what is wrong, if the part is new just returning it for a new one is the best you can do.

#

and try again.

#

maybe the CPU socket is damaged or faulty who knows

#

Whats your powers supply

#

GPU and CPU

inner hollow Jan 21, 2023, 1:24 PM

#

halcyon bone Whats your powers supply

I'm unsure

#

I have a ryzen 5 5600

#

And nvidia rtx 2060

halcyon bone Jan 21, 2023, 1:25 PM

#

Usualy says on the side of the powersupply what number is there

#

Big number

#

W

#

like 550W or 800W or what

#

cuz minimum what you need for that hungry AMD CPU is 650-1000W
with the GPU needing 550W minimum spec. Going mid range 800W power supply is good enough with 80 PLUS Gold efficiency

#

If you underpower your system this can be a result. Not detecting CPU or GPU

#

as its not getting enough power

inner hollow Jan 21, 2023, 1:29 PM

#

I don't think its a power related isue

#

My rgb and fans all work

halcyon bone Jan 21, 2023, 1:54 PM

#

than it can only be motherboard at this point if its not a power issue

#

and you are sure you tested all you could by guides

no mobo no gone
all turns on as per ur video

vapid ermine Jan 21, 2023, 4:01 PM

don't misguide
its only true of no components posting
his cpu socket is prolly damaged
the mobo is running rgb lights up

#

and fans too working as per his video

vapid ermine Jan 21, 2023, 4:02 PM

#

inner hollow I don't think its a power related isue

whats ur psu power?
and if not psu its forshure bent pins in the socket

halcyon bone Jan 21, 2023, 4:04 PM

#

He already checked and posted picture of cpu, it looks fine. Leaves me with cpu socket. I actualy had a dead motherboard with all lights and fans running

#

Power went thru but it was basicaly a brick

#

Still could be the psu but he didnt provided W so idk might be underpowered but we dont know

vapid ermine Jan 21, 2023, 4:08 PM

#

halcyon bone Still could be the psu but he didnt provided W so idk might be underpowered but ...

ok

vapid ermine Jan 21, 2023, 4:08 PM

#

halcyon bone Power went thru but it was basicaly a brick

ah

#

he needs to send a pic of psu and cpu socket

he died oof

halcyon bone Jan 21, 2023, 4:08 PM

#

Yea

#

And i returned my motherboard cuz it was fresh new as in his case they gave another one straight away and It worked fine later I received email that there was an issue from factory

#

It can happen that even maybe the cpu socket is just bad

#

Especialy on cheaper models

atomic hornet Jan 21, 2023, 4:16 PM

#

What is this connector for? Looks not correct on the pic 1! You have tested the motherboard in pic 2 without CPU? Why have you powered on the thing without CPU? Miss wiring can destroy something. Have you powered of the system while inserting the CPU?
I would try to disconnect everything you don't need for start from the motherboard for a test.
Can you send a pic of your full motherboard deployment and we can mark the things you should disconnect for a test.
At the end only MOBO, CPU and CPU Cooler, RAM and Power Button should be connected.

#

And the PSU to the MOBO I forgot.

halcyon bone Jan 21, 2023, 4:25 PM

#

Oh, good eye, I havent even noticed that, thats cpu fan header seems like, but can you even missplace that 👀

#

But on the video seems correctly placed

#

Could think of another way how not to make cpu work.
Plugging in PCI power cable into CPU on the motherboard

#

Can u even do that never tried, you can force it thats for sure

blazing vale Jan 21, 2023, 4:32 PM

#

does the motherboard support 5xxx series out of the box? Might just need a BIOS update

atomic hornet Jan 21, 2023, 4:47 PM

#

I cannot say which type of connector that is. It is not PCI power and I think it is not a FAN connector. If it shorted something, the motherboard is gone.

blazing vale Jan 21, 2023, 4:49 PM

#

yeah, was wondering why noone mentioned that ^^

blazing vale Jan 21, 2023, 4:50 PM

#

atomic hornet I cannot say which type of connector that is. It is not PCI power and I think it...

that should be a pump header on those msi b550 boards

#

There is also a screw missing there, stop being lazy, use all the motherboard screws

atomic hornet Jan 21, 2023, 4:58 PM

#

Not only the screw is missing. Also it misses standoffs!!! Fix your mounting!!! Disconnect the power supply while working on it!!! And hope that the motherboard is not gone!!!

halcyon bone Jan 21, 2023, 5:00 PM

#

Omg ok I guess we found culprit

blazing vale Jan 21, 2023, 5:03 PM

#

I still vote BIOS update, according to the compatibility list 5xxx was added later

#

but yeah, fix those standoffs

atomic hornet Jan 21, 2023, 5:06 PM

#

BIOS update after the MOBO is mounted correctly 👍

inner hollow Jan 21, 2023, 5:21 PM

#

those were old photos!

#

hahaha

#

yes mobo is properly screwed in and everything plugged in fine

#

however just tried the bios flashback method which i think is the problem

#

but...... the sequence is not begining when i press the button

blazing vale Jan 21, 2023, 5:24 PM

#

Which exact model board is that?

inner hollow Jan 21, 2023, 5:34 PM

#

the msi pro vdh wifi b550m

blazing vale Jan 21, 2023, 5:36 PM

#

so you followed the steps for it?

inner hollow Jan 21, 2023, 5:36 PM

#

yepp

#

downlaoded the file

#

renamed it

#

plugged it in

#

presed the button

#

nothing.

blazing vale Jan 21, 2023, 5:36 PM

#

PC was turned off when you pressed the button?

inner hollow Jan 21, 2023, 5:37 PM

#

no....

#

it was on

#

it has to recieve power to work no?

blazing vale Jan 21, 2023, 5:40 PM

#

power needs to be plugged in but system should be off, motherboard should turn on what it needs for flashback

#

also press and hold the button until it starts flashing

inner hollow Jan 21, 2023, 5:40 PM

#

oh yeah

#

its working now

#

thanks man

#

it flashed for a bit then everything just turned on

#

is that normal

#

flashed for like 2 secs

blazing vale Jan 21, 2023, 5:42 PM

#

once it is finished it restarts the motherboard once

#

also the USB stick should be formatted as FAT32

inner hollow Jan 21, 2023, 5:49 PM

#

yep

#

that was done

inner hollow Jan 21, 2023, 7:05 PM

#

But

#

When I did it

#

The red light never turned off. (Waited for over 10 mins)

#

My understanding is that it will turn off the light, then start all necessary components

#

@blazing vale

#

Any idea

blazing vale Jan 21, 2023, 7:08 PM

#

Hm, not sure

#

clear CMOS and try again?

inner hollow Jan 21, 2023, 7:11 PM

#

Hmmmmm

#

Ok

#

I'll give it a shot when I wake up tmr

halcyon bone Jan 22, 2023, 2:18 AM

#

ok I learned new things.

inner hollow Jan 22, 2023, 6:40 AM

#

ok

#

so

#

the light signalling the flashback bios did not turn off

#

its just staying on, which i believe means it isnt completed

inner hollow Jan 22, 2023, 8:28 AM

#

@atomic hornet any ideas

worthy hatch Jan 22, 2023, 10:45 AM

#

Did you try with no storage devices attached?
I once had a Samsung SSD that made my PC not boot if its attached.

spare canopy Jan 22, 2023, 11:58 AM

#

inner hollow the light signalling the flashback bios did not turn off

From other flashbacks it should just be continous on. Then its finished. that is usually around 5-6 minutes.

inner hollow Jan 22, 2023, 1:10 PM

#

FIXED LADS

#

mobo was fucked

#

got a new one

#

better than eve

#

ever

#

thanks everyone appreciate you loads
