No screen output at all

elder dome Sep 19, 2025, 2:47 PM

#

buoyant ridge Sep 19, 2025, 2:47 PM

#

It also doesnt turn on the keybord

#

Its still off when pc is on

#

I did a windows update yesterday, but i played some after the update and then turned pff my pc. Now it wont boot

#

Is this the cmos battery? Can i take it out?

#

Ive tried like everything now

#

Besides ripping out the cpu

buoyant ridge Sep 19, 2025, 3:11 PM

#

wheat edge reseat the CPU

Could you help me with this? What do i unscrew? Can i do it without reapplying thermalpaste? Do i have to rip of the cooler aswell?

wheat edge Sep 19, 2025, 3:24 PM

#

take off the cooler, yes

#

though hold on

#

you said it was working yesterday, but now it’s not?

buoyant ridge Sep 19, 2025, 3:24 PM

#

Yes

wheat edge Sep 19, 2025, 3:25 PM

#

Then it’s not a hardware issue most likely

buoyant ridge Sep 19, 2025, 3:25 PM

#

#

Ooga

wheat edge Sep 19, 2025, 3:25 PM

#

buoyant ridge Sep 19, 2025, 3:25 PM

#

Yes.

#

#

Yes?

wheat edge Sep 19, 2025, 3:25 PM

#

buoyant ridge Sep 19, 2025, 3:27 PM

#

wheat edge so you needn’t- well too late

#

What do i do

#

If i short theese when its powered on does that clear the cmos?

wheat edge Sep 19, 2025, 4:35 PM

#

buoyant ridge If i short theese when its powered on does that clear the cmos?

yes

#

while the pc is off tho

elder dome Sep 20, 2025, 2:54 PM

#

did u fix it? @buoyant ridge

buoyant ridge Sep 20, 2025, 6:37 PM

#

elder dome did u fix it? <@306033303658561536>

Nope. Ive tried everythihng almost

#

I swapped the aio out and it didnt work

elder dome Sep 20, 2025, 6:41 PM

#

the last option is to give ur pc to a computer service

#

if u already tried everything

#

i really dont understand what the problem is

#

i mean i heard about the windows update that fries ssd's

#

but

#

in your situation its not that

#

even the ssd is fried u have to boot to bios or screen with text "no bootable device"

#

when i installed my 2 different kits of ram

#

i kinda had the same problem

#

i mean it took like 5-10 minutes to boot

#

also the cpu light was on on the mb

#

but after all it boot up

#

u dont have spare ddr5 ram to try with them
