Question Why does a red screen appear when pressing F1 after updating the BIOS?

[Prime777]

I updated the BIOS of my ASUS PRIME H610M-K D4 motherboard from version 3403 to version 3601. Before this, I had installed the latest version of the ME Update Tool, although I'm not sure if the latest version was already installed. I had updated the BIOS a few times before, so I know how the BIOS update process works.

After updating the BIOS, the computer started up, and after the boot, I pressed F1 when the warning appeared. I don't remember what I pressed the last time I updated the BIOS, but I pressed F1, and the screen turned red without any text. After that, the screen turned black without any text. Then, I turned off the computer from the case and restarted it, and there was no issue. The BIOS was updated, XMP was disabled, and I enabled it.

From the System Information section in Windows, the BIOS version shows 3601, so it was updated.

Ideally you're advised to clear the CMOS after your BIOS flash was successfully executed. You disconnect from the wall and display, then remove the CMOS battery, press and hold the power button for 30 secs to drain any residual power then reseat the CMOS battery after 30 mins.

You will need to re-enable X.M.P and disable CSM if the latter's enabled in BIOS by default. Disregard the latter if you installed the OS with CSM enabled.

I've seen similar cases with other boards which tend to happen after a BIOS or OS or driver update. I would also make sure your OS is up to date as well.

Clearing the CMOS does only one thing: it clears out the memory that contains the BIOS settings, which a proper BIOS update does anyway, so unless there is a problem after the update, clearing the CMOS is not necessary.
