Latest BIOS Version?

[ARMCD]

My PC is an Intel DQ67SW which has the following BIOS version installed.

SWQ6710H.86A.0070.2018.1024.1352

Windows 11 update Stack Package will not install because it tells me "The PC must support secure boot - - (Version 922.415.111.0)" it goes on to state "We couldn't install updates because there's a problem with the date and time information on your device. Make sure your date, time, and time zone settings are correct and we'll try again later."

I have checked and made sure my PC has

"Set time automatically is ON"

"Set the time zone automatically is ON"

To be sure I hit the Sync Now and it was completed on 20 Nov 2025 @ 14:58:25 so I tried the update again with the same result.

On checking the installed BIOS the UEIF is set to ON in the BIOS

So my question is... Is there an updated BIOS for this motherboard and where can I find it?

Or is there another solution to this secure boot issue?

From what I can tell, you already have the latest bios.

I have attached it anyway.

Have you installed a new cmos battery, and set the date/time info in the bios?

Also, you know that your board and processor are not supported by W11, right?

You are indeed running on the final BIOS release for SW.
It sounds like you have an exhausted CMOS backup battery that needs replacing. This is a low-cost CR2032 battery that can be purchased practically anywhere. It goes into the battery holder on the motherboard.
Hope this helps,

Thank you for all your helpful comments which confirms my suspicions.

Looks like I am going to buy a new motherboard!!

Curious - what suspicion did we confirm?  Also, a CR2032 is pretty cheap compared to a motherboard.

And, a new motherboard means new memory, new processor, new cooler, and probably a new power supply.

Yea, I'm not sure what you think you had confirmed - but likely not correctly.

An exhausted CMOS battery simply means that the BIOS configuration - including its Secure Boot contents - will end up being reset to defaults on every cold boot. Each cold boot will be considered to be a CMOS Reset operation and a signal to initialize with a default configuration. Until you power on with a fresh CR2032 battery installed, you will see this issue.

I have a system with a similar 6 Series chipset (to be specific, the DZ68ZV) and it is, barring an issue with its graphics card, running Windows 11 just fine.

Hope this helps,

Thank you every one for your informative replies.

I think I have confirmed that

1. I should replace my CMOS battery as a first step.
2. My BIOS is the most recent for my board.
3. I should not replace the motherboard until I do step 1 above.
4. then consider next steps if not resolved.
