Asus Z170 Pro Gaming motherboard problem

Level 7
I have the MB mentioned in the title. Few days ago I decided to upgrade the drivers and I saw on the support site that my BIOS is behind too.

I had the 231 version and from BIOS using a USB Stick a update it to 803. All was good, install was successful but after restart the screen was black.

After a bit of tinkering I managed to load the bios from the USB stick and somehow it booted normally. A day passed without problems but now after a restart I got the black screen again.

What should I do? Any ideas? Please post here if you had a similar problem or maybe you know a fix.
I don't know what else to try.

Welcome to the forum!

Please list your other system components.
Did you revert back to bios to 231 and did you ever clear the CMOS?
What error code are you getting?

OS: WD Black SN850 1TB NVMe M.2
Storage: WD Blue SN550 2TB NVMe M.2
EVGA SuperNova 1200 P2

The rest of the componets are :

CPU : i5 6600K

I cleared the CMOS once. Yesterday I reverted to 231 I had on the Asus Support DVD. Now everything looks ok, at least for now, but I still can't understand what happened.
I get no error codes. Screen goes blank. After inserting the USB stick, the PC shuts down, then it starts again and then I get blank screen or it boots normally. Really weird.

I found the 0803 upgrade strange as well. I thought I broke it until I realized that since the cmos cleared it defaults to using the PCIE card which I have installed but I'm not using for my monitors since I use it for GPU passthrough to a windows VM with qemu. Needless to say I was quite scared for a while there.

Deviating off the topic slightly, for whatever reason I can't post my own thread so I did complete the 0803 upgrade from 0231 but now when I set my overclock of 4.7GHz on my 6700k to adaptive voltage I get less than stock! I even tried upping the voltage but still doesn't go past 39. I'm not convinced that i7z reads the core voltage correctly because I have it set to 1.38 with the offset on auto. But as you can see, multiplier is set to 47, but I'm at 100% and not going past 39 and temps are great at below 60 degrees. If I set voltage to manual or auto I have no issues (but obviously I don't want to leave it on auto or manual). With it the same but set to 45 I get even lower, 37x.
