Question Help Please. Motherboard CPU light on

[Sugua]

Hi there, built my computer about 2 years ago and haven't had any big issues.

Some time ago, i restarted it and it failed to boot. It failed to boot multiple times over a few hours so i gave up and went to sleep. The next day it booted up fine.

I'm today having the same issue, i was trying to update my bios using Gigabyte Control Center app, it restarted and i haven't been able to boot up since.

I notice there is an orange CPU light on my motherboard.

I've removed my RAM and reinserted (did not try to run only 1 RAM stick) (my configuration is in slots 2 and 4 as per manual https://download.gigabyte.com/FileL...1204_e.pdf?v=ee84ce5fae4b1bae08e94817d40cdb18)

Hardware:
CPU: i7-13700
GPU: Asrock Radeon RX 6950 XT Phant
Motherboard: Gigabyte Z790 AORUS ELITE AX ATX LGA1700 Motherboard
RAM: Corsair Vengeance 32 GB (2 x 16 GB) DDR5-6000 CL36 Memory
PSU: Cooler Master PSU V Series V750 Gold V2 (MPY-750V-AGBAG-EU) (MPY750VAGBAGEU)

If anyone can help me that would be greatly appreciated.
Thanks

My first suspect is the flash got nerfed. Unplug the power cord, press the power button to discharge the caps, and let it sit for an hour. It is supposed to load the backup bios automatically. So hopefully when you plug it back in and press the button it will load the backup. Next use the clear CMOS button on the board. If it still won't boot, you will need another system to download the latest bios and put it on a USB drive. Then you can use the Q-Flash plus button on the board to try to reflash the bios. As it does no require the CPU, GPU, or ram to work.

Still no joy? If your PSU came with a self power tester use it according to the directions. That will help determine if the PSU is at least working to some extent. As I've seen a fair number of owners have the Cooler Master series die prematurely on them. The RMA service experiences were mostly good, so that's encouraging if you have to replace it.

Reseating everything is always a good idea too. Power cables, ram, GPU, even CPU. It could probably use new thermal compound or a thermal pad by now. It's good to go barebones with no extra expansion cards or I/O stuff plugged in.

If nothing gets it to boot, the next suspect is the CPU. Raptor Lake is plagued by accelerated degradation. Perhaps you knew this and that's why you were trying to update the bios?

Good luck. Let us know how it turns out if you come back to this thread.

Thanks for the information.

Is it fixed?

hey been at work, just waited my 1h so will update once i've been through the steps here. thanks for your responses.

update: i'm going through the q-flash bios process, will update once done

 

[Sugua]

so i downloaded the latest bios here (FL). (confirming i have rev 1.1 motherboard)
i renamed the bios (the file ending in .FL) to "GIGABYTE.bin" and ejected my drive
with my computer switched off, i have inserted my drive into the BIOS USB slot and pushed the Q-Flash Plus button.

I've got a solid light on the q-flash indicator. everything online says this light should be blinking - it's been like this for 10mins+ now

i'm using a pretty big drive (external hdd 40GB). i'm reading that might have something to do with it.

i'm going to head out and buy a new drive, are there any requirements i should be aware of (other than not something this big)?

update: using a 32GB usb 2.0 drive and now have flashing light

 

[Sugua]

okay qflash successful!

computer has now booted up. thanks so much for your help as i was ready to give up and searching for tech shops in my area! (and thoroughly disappointed to see all the bad reviews!)

is there anything i can do at this point to check everything is working well/check the status of things?

 

[Sugua]

okay so apparently i'm not out of the woods just yet.

I just restarted again and the same boot failure happened. I checked the bios version prior to restarting and it had updated the latest one (which i qflashed).

I forced it to shut down (using power switch) and have turned on again..successfully now. scared to turn this off at this point.

update: so i'm unable to enter bios. every time i restart, if i press my bios key(s) it just doesn't boot, screens stay black. if i force power down and restart, it starts up back into windows (not every time)

I think if it is the CPU it would be more about crashing and reboots than cold boot issues, but certainly can't rule it out. It has symptoms of a flaky board. The cheapest route is to get a cheap PSU tester to make certain all of the rails are correct, and if they are I'd get a new board. EDIT: You can monitor them in windows with HwINFO64 while it is working. If the new board does not resolve the issues I'd RMA the CPU.

 

[Sugua]

what am i looking for in HWINFO64? i've installed

 

[Sugua]

okay so, i found some similar symptoms about not being able to enter bios here and i'm also using display port cable. i tried to update my gpu BIOS (i have latest drivers) but i'm unable to find the correct rom with my GPU part number (113-EXT700002-L01). the one i found apparently i already have installed

i replaced my display port cable with a HDMI, and was able to enter bios as expected. annoying though because i have 2 monitors and GPU only has one HDMI output.

do you know anything about the GPU bios issue i'm having (i.e not being able to find the correct rom).

If your 13700 is not an f model you have iGPU on it. So if you suspect it is a video card issue you can use it for troubleshooting purposes by plugging the cable into the one on the board. That'll keep you from going down another rabbit hole prematurely. Remove the GPU from the system when you do it.

PSU testers are cheap here in the U.S. and that will be the easiest way to know if it is faulty or not - https://www.amazon.com/Comidox-Computer-Supply-Tester-Automatic/dp/B07J9LRC6T/
