Question Ryzen 7 3700X Stuck at 0.55GHz After Fresh Windows Install – Works Fine in Safe Mode

[Wind_Stroke]

Hey everyone,
I'm running into a strange issue with my system and could really use some help or insight.
Specs:
CPU: Ryzen 7 3700X
Motherboard: ASUS TUF X570-PLUS (Wi-Fi) – BIOS updated to latest version
OS: Fresh install of Windows 10/11
Cooler: [mention if stock or aftermarket]
Power Plan: Tried both AMD Ryzen Balanced and High Performance

Problem:
After reinstalling Windows, my CPU is stuck at 0.55GHz, regardless of load. Temps seem normal and aren’t high. But the system runs super slow.
Here’s the weird part: When I boot into Safe Mode, the CPU runs normally and clocks seem fine.

What I've Tried So Far:
Updated motherboard BIOS to the latest version
Installed AMD Chipset Drivers from AMD’s website
Switched power plan to High Performance and set min/max processor state to 100%
Checked temps – nothing alarming
Booted into Safe Mode — works fine there
Disabled background services using msconfig (minimal change)
Planning to test disabling CPPC and Global C-States in BIOS next

Suspicions:
Seems like a power management or driver issue, since it behaves fine in Safe Mode
Could be a bad background process or Windows power setting that’s forcing a low idle state
Possibly chipset driver-related or something deeper in BIOS?

I'll attach a screenshot of HWInfo/Ryzen Master showing the clock and temp soon.
If anyone has run into something similar — or has suggestions for further debugging — I’d really appreciate it!
Thanks in advance

Let me know if you'd like to include anything else (like your PSU or cooler), and I can tweak it for you!

For the sake of relevance, please state the BIOS version for your motherboard at this moment of time.

OS: Fresh install of Windows 10/11
Where did you source the installers for your OS? Did you install the OS in offline mode? Installing all necessary drivers in an elevated command, while in offline mode?

Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:

Monitor:
include the age of the PSU apart from it's make and model.

I would look into clearing the CMOS and see if that changes anything. Then I'd try replacing the CMOS battery with a fresh cell.
