Thank you for posting your query on HP Support Community,
What is the product number of your HP notebook? Use this link to find it: https://support.hp.com/in-en/document/c03754824 (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).
Have you tried to run any test on the computer from F2?
Did you try to update the Bios on your PC?
Let's try these steps here:
Let's run an extensive system test from F2 (Please remember to capture the failure ID for further assistance).
If the test fails, then this clearly indicates a possible hardware failure with the notebook.
If the test passes, then I would suggest you try to update the Bios on your computer either from our HP support website, using this link or download it using HP Support Assistant.
I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...
HPSA will automatically search for all the latest drivers for your Notebook
Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
Click Check for updates and messages to scan for new updates.
Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
Click the update name for a description, version number, and file size.
Select the box next to any updates you want to install, and then click Download and install.
Also ensure Windows is up to date.
Select the Start button, and then go to Settings > Update & security > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available
Please let me know if this resolves the issue, or if you require further assistance!
If the information I've provided was helpful, give us some reinforcement by clicking the Accepted Solution and Kudos buttons, that'll help us and others see that we've got the answers!
Have a great day!

Thanks for your suggestion @Jeet_singh
I updated BIOS using HPSA, my Windows are up to date. It is still here; flow.exe is still eating up my CPU.
I guess many people are experiencing the same problem:
I will try their solutions.

You may follow the links and get back to us with the results for further assistance. However, I would suggest you try to uninstall the audio drivers and then reinstall it and check if that helps.
Right-Click on start button> click device manager> expand sound video and game controllers>then select the sound drivers and right-click on it and uninstall the audio drivers.
Then check the box delete the software for this device.
Now restart the computer and then update the Bios, Chipset and Audio drivers on your PC from our HP support website, using this link.
Let me know how it goes!
