A few months ago, with seemingly no reason (no hardware changes or incidents) my wife's gaming PC started pausing for 60 seconds+ before POSTing with the VGA fault light on. I tried everything, swapping GPUs, updating / resetting BIOS, replacing the CMOS battery, re-seating RAM and even the CPU itself, nothing worked. But it always POSTed, eventually. It's like it was memory training every time.
A few days ago it just stopped doing it, POSTing immediately like it hasn't done in months. WTAF
It makes me wonder whether Windows updates could cause / resolve something like this. I always assume the BIOS/POST sequence is too isolated for that to be the case, but with UEFI there's much more access from the OS - to the extent that updating a BIOS can now trigger a process in Windows on next boot (like asking you to install motherboard software). And I remember that Windows malware that could exploit your BIOS boot image. So perhaps it's possible?
@sinbad So... I USED to have ONE computer with Windows, for work purposes
A random day I inadvertently turned on this PC and, completely unattended, Windows decided to:
- update itself
- reboot the machine
- initiate an UEFI update
Except for me the UEFI update failed and bricked the entire computer (it was an ASUS mini-PC that has no sort of dual BIOS or recovery mechanism)
So it's very possible that Windows is messing with UEFI software entirely unprompted
I don't have Windows anymore smh
@sinbad I was like a month or two from the warranty expiring. In the end got sent an entire new PC but... yeah.... Absolute nonsense
