Black screen Monitor. pc boot up fine

[haughty osprey]

Can anyone help me. In the Afternoon, my monitor works just fine . Then I turned off the pc and went to sleep. When I wake up, the monitor doesn't turn on anymore 🥲

I tried:

• Turn off the PC and turn it back on

• Reset BIOS

• Turn off the power and turn it back on

• Check the monitor output and it was correct

• Remove all peripheral devices

• The screen is still working normally because it still says No Signal and the screen indicator is still on

• The monitor cable is a completely new cable

• removed the RAM and reseat them. even mount 1 stick only instead of 4

My main showing b2 code which i search to be related to GPU . My GPU works Just fine before . I do installed a Lian Li strimer v2 plus psu extension cable few days ago . However after installing and using for some days, my PC runs just fine until today it decided to not work anymore

Spec

Psu 850 w
RTX 3080
Z390 aorus Master

your psu has the minimum wattage for the gpu, however you stated it still worked before. so one moment while i look up your code

can you confirm your GPU with another pc?

[haughty osprey]

Sorry i can't. I don't have another case for testing 😭

[unreal oracle]

ok...

[haughty osprey]

I do plug my gpu to my laptop to try projecting it on the laptop but it doesn't work either

[unreal oracle]

when you turn the pc on do you hear any beeps

[unreal oracle]

most likely your gpu than, how old is it

[haughty osprey]

I don't hear any sound but it could be the fans so loud it overshadow the beep noise

[haughty osprey]

It's Brand new . I RMA my old one and got this brand new around last year

The end of last year

I did some research and Sometimes it could be these lian li cable

But i am no good in taking things apart so I'll wait till tomorrow to get an employee here try taking it apart

[unreal oracle]

where abouts do you live? Canada or the US? im a pc tech and do repairs?

im in Canada

p.s. i dont have a shipping address yet... im working on that

[haughty osprey]

Also my peripheral RGB don't Light up after booting the PC so i think the Pc can't even boot into windows

Ahh thank you for your help but I'm in SEA. 🥲

[unreal oracle]

not necicarily

well

actually thats mostly the case... either your psu or northbridge chipset is fried

[haughty osprey]

And i thought if anything here was fried , it's my GPU cause if the PSU is dead , i don't think it can even boot at all , same for CPU. And my Monitor output is the hdmi slot on the GPU

[unreal oracle]

does the motherboard have onboard graphics?

aka a hdmi port etc etc on the motherboard?

if so plug the moniter in there and that will tell you if the gpu is dead

[haughty osprey]

It has but the default setting for it is disabled and i just reset my Bios so technically I can't access the Bios at all until i have a new GPU or fix whatever is happening

[unreal oracle]

i dont have expirience with RGB so i had to look it up but your rgb needs the processor to run so if the onboard graphics doesnt work your northbridge is dead

[unreal oracle]

crap

hmmm ok im gonna look something up

GIGABYTE Z390 correct?

[haughty osprey]

Yes

[haughty osprey]

@unreal oracle

[unreal oracle]

[unreal oracle]

[haughty osprey]
