Check the 24 pin cable and the CPU power cable

haughty elbow Oct 22, 2024, 9:01 PM

#

They are firmly attached

haughty elbow Oct 22, 2024, 9:21 PM

I have tried, Putting all cables out and in, putting in ram in different slots and keeping 1 in, removing ssd, only keeping mobo and cpu in, also i tried resetting bios with the battery but i think i did that incorrectly

#

to reset the bios using the battery

unplug the psu and then hold the power button down to drain the capacitors
remove the battery for 10 seconds
replace the battery
power on the pc again

#

Thanks i will try this tomorrow i have building/trying to fix the pc since 5 hours ago so im drained.

#

Also open for any other things i could try if resetting the bios doesnt work that i could try tomorrow but i am gonna sleep now good night

#

The pc will keep staying on if i unplug the cpu

#

Is this a cpu issue or a mobo issue?

cold raft Oct 23, 2024, 10:06 AM

#

Did you try putting the CPU cable back in now?

haughty elbow Oct 23, 2024, 10:51 AM

#

Yes and it will shut down after a few seconds aigan

haughty elbow Oct 23, 2024, 11:40 AM

#

What could i try i dont have a spare amd mobo or amd cpu

#

Can also be something as simple as a sata cable not being fully attached

haughty elbow Oct 23, 2024, 12:16 PM

#

I use an m.2 ssd that doesnt require any sata cables right?

haughty elbow Oct 23, 2024, 2:06 PM

#

Im gonna try putting in the cpu aigan and cleaning everything checking the pins etc

cold raft Oct 23, 2024, 2:09 PM

#

If the CPU was the issue the CPU debug light would be on

haughty elbow Oct 23, 2024, 2:16 PM

#

Could it be the motherboard needs a bios update?

cold raft Oct 23, 2024, 2:24 PM

#

Maybe try individual ram sticks

haughty elbow Oct 23, 2024, 2:25 PM

#

Already tried

haughty elbow Oct 23, 2024, 2:28 PM

#

haughty elbow Could it be the motherboard needs a bios update?

Is this possible with the 5 3600 and the b450m pro r2.0

cold raft Oct 23, 2024, 3:20 PM

#

No it's should be fine out the box

#

But you can try

haughty elbow Oct 23, 2024, 4:39 PM

#

Mobo and cpu are both used

haughty elbow Oct 23, 2024, 5:07 PM

#

cold raft But you can try

How do i update it tho😭

#

I got no spare 1k or 2k series

frosty iris Oct 23, 2024, 5:13 PM

#

Unless it has bios flashback, you can’t

cold raft Oct 23, 2024, 7:03 PM

#

I highly doubt updating the bios would fix it

faint yoke Oct 24, 2024, 12:18 PM

#

haughty elbow How do i update it tho😭

Try booting with only 1 stick of ram, try each one

#

Maybe one is faulty

frosty iris Oct 24, 2024, 1:59 PM

#

Did that

cold raft Oct 24, 2024, 3:00 PM

#

I guess you can check if you have any bent pins
