Doing a new build featuring the Z690 Dark Kingpin motherboard. Did a clean Windows 10 install. Every few seconds, a device called EVGA Z690 MCU appears in the Windows device list, then disappears. System stutters for a moment. Repeats every few seconds. System is unusable for gaming due to the stuttering.

Any help or suggestions greatly appreciated... Tks...

Hi LeeM. Thanks for the reply. Yes all drivers are installed from the USB key that came with the board.
 
Based on your suggestion I updated the Intel ME drivers to most recent version 2216.16.0.2805 dated 6/15/2022. The version on USB was 2131.1.4.0 dated 7/27/2021. 
 
Unfortunately the problem persists. Please let me know if I should try anything else. Or should I RMA the board at this point?
 
Thanks for your help, LeeM. And thanks for being there doing what you do. You are awesome on this forum... cheers :)

Hi LeeM! Just submitted the RMA request. Thank you very much! Hopefully I will get a survey to report all your awesome support. If there is another method I can use to give positive feedback, please let me know.  Have a great day, LeeM :)
