And can you get to BIOS?

#

gleaming sigil Did you set the boot option correctly?

#

SO if your PC doesn't post, then there's a different problem

dawn dock Aug 23, 2023, 5:21 PM

#

what could it be

gleaming sigil Aug 23, 2023, 5:21 PM

#

So you said it doesn't post at all?

dawn dock Aug 23, 2023, 5:22 PM

#

does post mean like start

#

power button does nothing

#

like no lights or no fans spin when i press it (psu is on)

gleaming sigil Aug 23, 2023, 5:22 PM

#

Yeah

#

Are your FP connectors plugged in at the right spot

dawn dock Aug 23, 2023, 5:23 PM

#

im not sure about the power button cable

#

wait ill send a image

gleaming sigil Aug 23, 2023, 5:23 PM

#

I will also need the exact mobo model to be able to judge if they're plugged in correctly

dawn dock Aug 23, 2023, 5:24 PM

#

#

gigabyte b550 aorus elite v2

gleaming sigil Aug 23, 2023, 5:25 PM

#

you're not plugged in right as far as I can tell

dawn dock Aug 23, 2023, 5:26 PM

#

which one might be in a wrong spot

#

#

this cable im kinda weirded out by

#

the manual makes no sence

gleaming sigil Aug 23, 2023, 5:27 PM

#

Can you unplug and short the pins with a screwdriver?

dawn dock Aug 23, 2023, 5:28 PM

#

like hold a screwdriver on them?

gleaming sigil Aug 23, 2023, 5:28 PM

#

So unplug the FP cable and make sure to use a screwdriver to make contact between the power switch pins

dawn dock Aug 23, 2023, 5:29 PM

#

do i turn the power on

#

on psu

gleaming sigil Aug 23, 2023, 5:29 PM

#

This is essentially what a power button does

#

yes

dawn dock Aug 23, 2023, 5:29 PM

#

and do i put usb stick in

gleaming sigil Aug 23, 2023, 5:29 PM

#

Because you essentially emulate the power button like that

#

I would not

dawn dock Aug 23, 2023, 5:29 PM

#

but my friend said that nothing will happen

gleaming sigil Aug 23, 2023, 5:29 PM

#

Do make sure to plug a Keyboard and screen in and start spamming delete if it turns on

dawn dock Aug 23, 2023, 5:29 PM

#

because the pc has not "operating system"

gleaming sigil Aug 23, 2023, 5:30 PM

#

Ahh you can get to BIOS

dawn dock Aug 23, 2023, 5:30 PM

#

no i cant

#

XD

#

i cant get to anywhere

gleaming sigil Aug 23, 2023, 5:30 PM

#

I mean you can get to BIOS if the PC posts

dawn dock Aug 23, 2023, 5:30 PM

#

ok ill try this

#

screwdriver thing

gleaming sigil Aug 23, 2023, 5:30 PM

#

That's why you should spam delete if the fans start spinning

dawn dock Aug 23, 2023, 5:31 PM

#

should i hold it on the pins

#

or like lightly hover above

#

i dont want to get like electrocuted or something

gleaming sigil Aug 23, 2023, 5:31 PM

#

Make direct contact with the two that are labeled Power_Switch

#

So when facing it form the front, the 3rd and 4th pin in the upper row from the left

dawn dock Aug 23, 2023, 5:32 PM

#

i dont see it label that anywhere

#

oh

gleaming sigil Aug 23, 2023, 5:33 PM

#

It says PW

dawn dock Aug 23, 2023, 5:35 PM

#

so i hold the screwdriver there and then what

gleaming sigil Aug 23, 2023, 5:35 PM

#

It should turn on, then you can remove it

dawn dock Aug 23, 2023, 5:36 PM

#

Nothing happens

#

gleaming sigil Aug 23, 2023, 5:37 PM

#

Turn it around slightly and see if it works (so like wiggle it a little). May be that they don't make contact properly

#

When building a PC open-air, I always use a screw driver to turn it on. Sometimes screwdrivers also have electrically insulated (especially Philips head). If you have a flathead one, try that

dawn dock Aug 23, 2023, 5:41 PM

#

it seems to not do anything

#

hmm

gleaming sigil Aug 23, 2023, 5:43 PM

#

Okay, then verify that you have the 24-pin and 8-pin EPS cable plugged in all the way. Can you additionally give me some more specs for your PC? PSU, CPU, GPU?

gleaming sigil Aug 23, 2023, 5:43 PM

#

dawn dock it seems to not do anything

Now there's probably a hardware problem

#

But you did update the BIOS you said?

#

If the PC didn't turn on, how would you have done that, also that board doesn't have BIOS flashback afaik

#

It has damn

dawn dock Aug 23, 2023, 5:44 PM

#

gleaming sigil Aug 23, 2023, 5:45 PM

#

Why did you update the BIOS in the first place?

#

Can you try to update it once again?

dawn dock Aug 23, 2023, 5:45 PM

#

friend said it could be something about like old update not supporting the parts

gleaming sigil Aug 23, 2023, 5:45 PM

#

What's your CPU?

dawn dock Aug 23, 2023, 5:45 PM

#

ryzen 7 5800x3d

gleaming sigil Aug 23, 2023, 5:46 PM

#

I c

#

But why not try and then, if it doesn't work update? Because I have a bad feeling about this. I am actually more and more feeling like that board is bricked
