HI to all of you

i have this motherboard P67 EXTREME4 https://www.asrock.com/mb/Intel/P67%20Extreme4/index.asp

2 years ago i updated to i5-2500K cpu and 2 modules of 8gb ram each 2X8=16gb total ram

i had issues with the ram performance and i found a new modded bios for this mobo from hear https://www.mdclab.it/intel-socket-1155-p67-extreme-4.html

i downloaded and installed and was all good until yesterday

i decided updating from win 7 to win 10 but i have a strange issue

with both installations uefi and legacy bios the pc don't turn off

pushing the shutdown button or from os power->shut down

the monitor is shutting down and the power from keyboard and mouse but the pc still have power i have to push the power button continuously to turn it off

i think bios needs updating can someone help to mod it?

Did you loaded "setup defaults" after flashing 2 years ago ?
pls do it, reconfigure the whole bios and look for options like "power ac loss" and other options.
did you boot legacy or UEFI Mode ? Also a BIOS Option.....

yes i setup defaults after flashing 2 years ago

i found the solution after some search i was right about the bios .i found a bios P67EXT43.21A have the bios logo of asrock fatality but who cares?

so i think P67EXT43.19 bios missing some drivers for win 10 that's why don't power off

Hello,
Can you say me where to find this P67EXT43.21A BIOS.
Thanks
