Hi, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today, my working hours vary & I usually reply between 10:00 pm & 6:00 am EST(UTC -5) Monday to Sunday.

I understand the issue you have, there is nothing to worry I am here to help, this issue is due to unnecessary third-party services running in the background or there is overheating from the processor, for us to sort out the issue, kindly follow the steps below:

Method 1. Do clean boot:

A “clean boot” starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program.

• In the search box on the taskbar, type msconfig and select System Configuration from the results.
• On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
• On the Startup tab of System Configuration, select Open Task Manager.
• Under Startup in Task Manager, for each startup item, select the item and then select Disable.
• Close Task Manager.
• On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.

Method 2. Run Intel Diagnostic tool:

Go to this link: https://www.intel.com/content/www/us/en/downloa...

Then download and run the tool.

Suppose there is any failure on the test. In that case, that means there is a hardware issue on your processor, which needs to contact Intel support or a local technician on the next step, which might be a processor replacement or board depending on the diagnosis on the hardware.
