I recently discovered after rebuilding my PC that the CPU clock speed has increased significantly. In the screenshot I captured, I restarted the system with no open applications or games. The speed jumped from 4.10ghz to 4.20ghz. My CPU’s base speed is listed as 3.59ghz according to the BIOS. I’m not attempting to overclock it. I’ve adjusted the BIOS settings back to default, but the speed remains at 4.20ghz. On other machines, lowering clock speeds was possible by changing power settings to power saving. This doesn’t seem to work here. Although turbo boosting exists, it shouldn’t be active when the PC is idle. Is this normal or problematic, and how can I bring the clock down?

Default means PBO on. So there is nothing bad or something to worry about here. Your idle CPU has 15 to 30% load on it, its not "idling".

I closed all of the processes in the background. I guess this is better then?

PBO [ON] appears to be the reason for your clock speed changes, even when usage stays low at 2%. Your CPU frequency keeps shifting in that way.

PBO enables your CPU to operate at faster clock rates beyond its base frequency. C will lower the CPU's speed and voltage to minimize energy use.
