    Hi Michael,

    High CPU(Central Processing Unit) Usage May Be Caused By:

    a: Out-of-date drivers

    b: Running too many applications at once

    c: Insufficient virtual memory

    d: Overheating/Poor ventilation

    e: Virus/Malware infections

    Method 1: Update a driver for hardware that isn't working properly

    **http://windows.microsoft.com/en-us/windows/update-driver-hardware-isnt-working-properly#update-driver-hardware-isnt-working-properly=windows-7**

    Method 2:

    Run the Microsoft Safety Scanner in full scan mode, and remove all the threats that get detected by it and see if the issue persists.

    **Microsoft Safety Scanner**

    Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.

    The Microsoft Safety Scanner is not a replacement for using an antivirus software program that provides ongoing protection.

    Please take a backup of all the data to an external hard disk before performing a scan as it could result in data loss.

    If you need any further assistance with Windows Operating System, please post your query on Microsoft Community Forums and we’ll be glad to assist you with it.
