System Idle Process High CPU Usage

Question

I had a Windows 7 Professional and then thought about upgrading to Windows 10 since Windows 7 is coming to end. When I upgraded to Windows 10 i got a random Blue Screen. My PC restarted i opened Task Manager and there it is 100% CPU Usage non-stop. Its really annoying i read the same problem of some guy on this kinda forum, and followed his steps. None of them worked and i'm really annoyed by Windows 10. This never happened on Windows 7 and i'm really hoping there is a way to fix this.

My PC:

CPU: Intel Core i5 2400 3,10GHz

RAM:12GB(4x3)

Graphics Card: Nvidia Geforce GTX 1050 Ti 4GB GDDR5

HDD:1TB

I found out that System Idle Process is taking too much CPU how can I fix this?

Waiting for help.

You must do it the way I mentioned before:

Boot the machine with the Media Creation Tool

In other words, you must make the USB flash disk your primary boot device.

Answer 5

With puzzling cases like this I see these options for you:

• Ask a computer-savvy friend to examine the machine.
• Have the machine serviced.
• Grant me remote access so that I can have a close look by myself.
