HP 580-137C stucks at 0.54GHz

[Will-Plano]

After the computer wakes up from sleep mode, the CPU speed is stuck at 0.54GHz. I checked the speed from both Task Manager and AMD Ryzen Master. They are same.

Sometime, even just fresh powered up, the CPU speed is stuck at 0.54GHz too. 

I got this PC about a year ago,  noticed this problem 4 monthes ago. Not sure if the problem exist when I got it. 

Please help......

Thank you for posting on the HP Support Community.

I have a few troubleshooting steps we could try to fix the issue:  

Let's perform Windows Update and HP Support Assistant:

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

And, also update BIOS: Follow steps from the link: https://support.hp.com/in-en/document/c00042629
