Product: HP Pavilion - 15t-cs300 CTO
Operating System: Microsoft Windows 11

I keep getting an error that the hpchix64.sys driver cannot be installed, which has been appearing since I upgraded from W10 to W11 (Windows 11 Pro v22H2, with OS build of 22621.1485) in October 2022.   Even since then my laptop screen keeps continuously blinking on and off whenever it is processing something, so can only use it with an externally attached monitor now.   Cannot find anything concerning the hpchix64.sys driver, so am wondering if this is a legit HP driver that needs to be installed or not.    Thank you.
