Thank you for contacting the Intel community.
Have you tried with different mouse?
Try running Windows update; I have seen some customer solving the PCH fail result by reinstalling the Intel® Processor Diagnostic Tool.
It is hard to determine if the PCH fail result is causing this problem, this curser issue can also be cause by the RAM, have you tried reseating the RAM or if you have two RAMs installed try one at a time.
I hope this can help.
The unit is end of interactive support but Intel provides three years warranty from the moment the purchase is made.
The support is working right now so you can either create a online service request or you can do live chat.
Please let me know if you can access the website.
I tried repeatedly to access the website. I sign in with no problem, but when I attempt to create a support ticket it tells me that it doesn't recognize the product, despite providing the correct Stocking ID. My info is:G6YK41500FBL
