All right, I finally fixed my problem!
I reverted to BIOS 1201, thanks a lot aaraujo for your help!
Turns out that didn't actually fix the problem.
I cannot exactly pin point what caused the issue, but it looks like it might have been related to one of those 2 things:
- My CPU fan isn't connected direclty to the motherboard (it's managed by the case).
That means with the default BIOS settings, the motherboard won't boot and forces me to disable the CPU fan monitoring in the BIOS, after pressing F1.
- My system is configured with an NVMe RAID Array
It looks like if I don't set the SVM Mode before setting up both the RAID array and disabling CPU Fan monitoring, then I can't set it up later... (although this isn't 100% proof)
Switching back to version 2008, I was still able to enable SVM Mode, after a few tries.
But after using version 2008 for a few days, I get regular crashes, which make the PC completely frozen, and even holding the power button for 20s doesn't stop it! Never seen that before, I must say... I actually have to switch the PSU off to unfreeze the PC.
So, long story short, I'm back to version 1201... Anyone had similar freeze issues with the 2008 BIOS?
