I have a HP Pavilion 15-Au023cl . This past week, the touchpad started becoming lagging at some moments, and intermittent at other times. The screen occasionally flashes on and off, and once seemed to turn on and off. I think that regarding the screen, that it started doing that after a Windows 10 update. It is possible that I may have updated the graphics card. The last one that I have is Intel HD Graphics 520 version 220.127.116.1149. The HP website has an NVidia driver from 2018, and an intel HD Graphics driver from 2018, but it doesn't say 520, so I am not sure that the latter one is for the same card. I also do not know why it says NVidia when my system does not even mention NVidia. Any advice would be appreciated.
