Hi, I have problem with my All in One 

I install clear windows 10 64bit, after install I connect PC to internet and install all drivers and updates.

My problem starts when I install Bios version 15.74.0.0 (additionals updates -  HP Inc. Firmware 15.74.0.0). After install, my computer have problem with graphics and blinkong display with Integrated graphics 

I have currently F.74 BIOS Version, but in HP Website is latest version F.67 Rev. A

Can you provide a link to where you obtained the 74 bios?  I was unable to find it when looking here

Some BIOS, once installed, cannot be downgraded.  I can walk you through a downgrade but first lets see if the graphics problem can be fixed.

The version 67 bios is for windows 10 build 1809

There is a chipset driver that is is designed for build 1809.  See if this helps

I did not see any intel graphics drivers for build 1809 unfortunately.

Since you have internal graphics then Intel driver is the one to use. 

If the chipset driver does not help then run MSINFO from the windows search

look for the phrase Braswell or Apollo Lake in the Intel graphics information page

if you see Braswell then use the BSW driver

If Apollo Lake then the APL driver

else the one that does list mention APL or BS.

you will need to select the 1809 build of windows 10x64

if none of these fix the problem post back here and we can try reverting the bios
