HP Recommended
Operating System: Microsoft Windows 11

HP Windows 11 Pavillion Laptop would not talk on the network so I noticed a Windows Security Core memory problem and performed the action to fix it.  It fixed the network problem then when I rebooted the Laptop the bluetooth mouse was no longer configured so I configured it and rebooted then the screen was not usable, going black then coming back. After trying a few things I found that by holding the power button down until the Laptop powers off and then rebooting fixes the problem unless I power down normally.  The only fix to force the power off.  Looking at the log I have a Iommu Event ID 15 Source HAL error when rebooting, actually lots of them.  Do I need to reinstall hardware drivers and what is the proceedure?
