After that 6 device have exclamation marks on 1 ethrnet control, pci data acquisition And signal processing controller, universal serial bus controller, pci simple communications controller, sm bus controller and 3 unknown devices.

Welcome to HP Community

I have gone through your Post and would like to help
 

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

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.

Keep me posted how it goes

Thank you and have a wonderful day 😊
