    PCH Fail on NUC D54250WYKH1 D54250WYB  Board


      I've had a recurring, intermittent problem with the cursor locking in place at the top middle of my monitor, blinking at about 2Hz. Updating drives, rebooting, etc. haven't solved the problem.


      Today I downloaded and ran the Intel Processor Diagnostic Tool.  It reported the PCH test failed.


      System Information



      D54250WYB  Board

      Processor Intel Core i5-4250U

      Windows 10 - up to date

      Intel Driver update tool says all drivers up to date

      Windows Memory test says no problems.

      I found a suggestion for a fix at Tom's Hardware, but I couldn't get at the motherboard battery to try it.

           Intel diagnostic tool PCH fail. - [Solved] - CPUs



      1) Is my blinking cursor problem likely to be caused by the PCH failure problem?

      2) What can I do to fix the PCH failure?
