Gigabyte z390 aorus pro bios update to f9b fail

[mididim]

Hello! 
Just recieved z390 aorus pro rev 1.0,and have a new build done successfully with bios f5 (default on mb) 

I9 9900k
16gb ddr4 cl15 2666 hyper x
Evga gtx1070 sc
Be quite shadow rock 2 
Corsair rm550x 

On first launch with bios f5 i was able to enter bios setup as usual. 
But attempting to install windows 10 gave me BSOD, blue screen. 
So i downloaded recent bios version f9b, and flashed thru bios utility q flash. 
After sequence completed and automatically restarted - black screen, nothing... 
On motherboard red vga (left lower corner) is lightning... 
Tried cmos reset with screwdriver, nothing. Tried remove gtx1070 and connect via onboard hdmi... Nothing... 

What can i do?

Thank you for the link. 

Helped. 

Now if experiments with bios causing black  screen - pressing power button for a few secods initiates start stop sequence and restarting pc resets bios. 

 

But after bios flash , it took a while and many attempts before board showed bios... Pfff. 

 

Now my i9 9900k is working, but very strange. With default bios settings pc won't boot, till i turn turbo enhancement, turbo boost off. Max i can get 3.9 ghz manually entering in bios. 

 

Have Changed psu to corsair hx850 since first post, same result. 

Over 3.9ghz on all cores causes blue screen. 

Where to start? 

I'm noob in bios settings. 

 

Is it possible that ram or... Any HW component is incompatible with 9900k?

Or it is a bad cpu chip? Can it be? 

 

Can anyone help me with bios settings for i9 9900k on gigabyte z390 aorus pro? 

Thanks
