  • Hello,


    Thank you for posting!


    To accurately troubleshoot this issue, I recommend you to use the following tool to analyze the status of the processor:


    Intel Processor Identification Utility


    Install and launch the tool after downloading, then click File and select Save to export the information into a text file. Open the text file and paste all the information into your reply, if possible.


    Thanks for your cooperation!
