Whenever you replace the PCH the intel ME firmware must be cleaned in the bios. Here`s some guides https://www.badcaps.net/forum/troubl...22#post1622422 . If you can`t do it yourself post a request in the bios requests forum -

Hello everyone,
About a year ago, I accidentally erased the firmware on the SPI ROM of a Thunderbolt retimer in my computer, mistaking it for the main BIOS chip. Since then, the Thunderbolt controller no longer appears in Device Manager, and I'm unable to use Thunderbolt functionality.
For context, my system has two retimers: UT5 and UT3. The one I erased is the UT3, which uses a W25Q80DVSSIG chip. In an attempt to fix this, I used a CH341A programmer to copy the ROM data from the UT5 retimer to the UT3, hoping it would restore functionality. Unfortunately, this didn't... -
