According to your description, I suggest you refer to the following information:
1. Please recall what actions usually cause this phenomenon, such as whether special third-party software is installed or after hardware changes (such as adding new memory). If so, you can try to uninstall the corresponding software and restore the previous hardware configuration. If you connect external devices, such as external cameras, printers and USB mice and keyboards, it is recommended that you disconnect all external devices and try.
2. You can also press the F8 key to enter the safe mode to test whether there is such automatic power failure. If there is no such phenomenon, it will only happen after entering the system. Then, if you don't have any special startup items, I suggest that you can disable all startup items and services after entering the system normally. Methods: Please click on the Start menu, enter msconfig during operation, open the system configuration, disable all the services in the startup item, then hide all the Microsoft services in the service, and then try to disable them all. After you restart your computer, test whether this phenomenon exists, lest it be caused by the poor compatibility of some previous programs.
Please disinfect the system to avoid system poisoning.
4. If the driver you installed is not downloaded from HP official website, I suggest you try to install the driver released by HP official website. For how to download the driver of the corresponding product from HP official website, I suggest you refer to the following official documents:
