Curiously, I was in the middle of some work this evening when my PC suddenly went to black screen with some disk activity - then it rebooted, showing the message "BIOS is updating. Do not shut down or reset the system to prevent system bootup failure."
This happened twice - the routine did something, rebooted, showed same message then rebooted, then POSTed as usual.
The board is a Maximus XI Hero, fairly recently installed.
There were no Windows prompts or warnings, nor did I request this to be done.
I have Armoury crate installed (which comes from the motherboard's
UEFI WPBT portion of the firmware as I understand it?!) -- frankly I find this ridiculous. I did wonder how Armoury Crate magically appeared after first boot, I suspected it was just Windows Update being helpful at the time so didn't investigate further.
Surely a BIOS update shouldn't just happen without warning in the middle of the evening? Have all the usual protections, antivirus, firewall and I carefully monitor my system's activity. Very curious, and I'm worried about it happening again in future. I can see two BIOS updates available (as .zip files) in Armoury in the BIOS section, the most recent is from last year which I'm already running.
As my board and CPU was OCed as a pair by the retailer, I want to prevent any automated or blind BIOS updates which might destabilise the overclock or cause other nasties. Quite worried now that I have a board which just updates its own firmware as and when it feels like it. Or is this something to do with a bad OC partly corrupting the BIOS and Flashback is automatically restoring it to a good state? The feedback on-screen was useless so I don't know what's going on. There was no sign of a firmware update in Windows Update history though...
The machine was running stably with nothing intensive going on, temps all normal and clock speeds well in reasonable limits.
