Hi,
Thank you for posting your issue on Microsoft Community Forums.
 
1. Did you make any changes to the computer prior to the issue?
2. What is the make and model of the computer?
3. Is the computer on a domain network?
 
High CPU consumption by these activities [interrupts and DPCs] can indicate a hardware problem or issues with the device driver.
 
Method 1:
I would suggest you to update the chipset and BIOS drivers on the computer and check if it helps.
Refer:
Also, try to download and install the latest chipset and BIOS drivers for the computer from the manufacturer's website.
 
Method 2:
I would ask you to check if the issue persists after disconnecting all external devices (except mouse and keyboard).
 
Method 3:
Run hardware and device troubleshooter.
 
Method 4:
Check if issue occurs in clean boot.
Refer:
How to perform a clean boot to troubleshoot a problem in Windows Vista, Windows 7, or Windows 8

Note: Refer "How to reset the computer to start as usual after troubleshooting with clean boot"
under more information to reset the computer to start as normal after troubleshooting.
