Question ASRock X670 Taichi Carrara issue

[airgreek]

Hello,

I built a new pc back in July 2024 and I have been having issues with random reboots into the bios screen. I can run fine for a day sometimes two with no issue. These random reboots seem to happen when my PC sits idle for hours. I have the latest bios installed. My original build was:
7950X3D
64 Gigs (2x32) CL30 6000mhz ram G skill Trident Z5 NEO RGB Ram
Founder 4090 video card
Seasonic 1000W Platinum Prime Power Supply
Asrock X670 Taichi Carrara motherboard

Revised built is :
9800X3D
32 gigs (2x16) Kingston Furry CL30 CL30 6000mhz ram
Founder 4090
Seasonic 1200W Platinum Prime Power Supply
Asrock X670 Taichi Carrrara motherboard

Still having the same issue. I tried different settings in the bios but no luck, I am assuming it is the motherboard? I have not tried to slow down my ram from 6000mhz to 5200mhz. Any suggestions?

What are your temps like?

Check Event Viewer and Reliability History for helpful info from the system. Expect Event 41.

Run SFC/DISM and see if it helps.

why did you switch to the new lower quantity RAM, previously having issues?

and make sure you have the latest BIOS installed.
it could be your AsRock motherboard control software is trying to update and failing.

I have the latest bios installed
For the sake of relevance, are you on BIOS version 3.10?

How are you cooling the processor? As for your memory, since you swapped them to a different kit, are the rams populating slots A2 and B2?

Out of curiosity, did you migrate anything over from your last build(if you had any)?

I switched back to the gskill ram. Still same issue. I am on Bios 3.10. I am using a Noctua NH-U12A for cpu cooler. CPU temps are fine. Everything was migrated. The only thing that I have not changed is the motherboard and video card. Windows Resource Protection did not find any integrity violations.

There is nothing wrong with your motherboard, you have done something wrong, it would be easier to say that the power cable of the graphics card is at fault or even the card itself

have you ever been present when the system shuts down/restarts into this scenario?
if so, do you notice anything particular happening;
or does the screen just go black,
system restarts out of nowhere, etc..?

check all Windows Power settings,
try changing any Standby/Sleep options to disabled.

if this stops the issue from occurring then you know there was an issue with the OS.

anyway, i would definitely try going through the DISM and System File Checker(SFC) routines.
if hardware was failing then you'd likely be noticing much more problems than just a random reboot to BIOS when you're not using the system.
i would imagine it is a problem with the OS itself.
