CPU won't go above 23% utilization

I have a custom built PC. specs are below. After some recent problems and a full windows reinstall it seems that my CPU won't go above 23% utilization. I have set the power plan to high performance and am using Prime95 to attempt to stress the CPU. When
I look in the BIOS everything looks correct. The CPU temp is reasonable, it detects the CPU as 3.4ghz. Windows also detects that the model of the CPU is correct and lists it as 3.4ghz in system properties. When viewing the CPU on the performance tab of
task manager is lists the speed as 0.78 GHz and that number never changes. It's like it's stuck on that number. Any help on how to troubleshoot this problem would be appreciated!

CPU: Core I7-6700 @ 3.4ghz

Motherboard: Gigabyte GA-H170M-DS3H

Bios Version: F22e (latest)

Graphics: Onboard Intel 530

RAM: 16gb DDR4 2133

PSU: 550w

Power plan: High performance

Edit:

Additional Troubleshooting steps:

Reset BIOS to default values - Issue still occurs.

CPU utilization >100%

Hi,

Thank you for being a part of Windows 10.

The issue could be due to some Software/update causing the issue. I would suggest you to press the
Shift key and hold the power button so that it will go to the
recovery options, Select safe mode and boot to the desktop. Once you are able to boot to the desktop, check for the CPU utilization.

Hope this helps. Let us know if you have any other issues with Windows in future.
