I was working on one of my users desktops (adding RAM). The machine wasn’t recognizing all of it. I eventually cave and call tech support. Their solution was to not use all of the RAM slots. I called up the next day and got a competent person to replace the board, but pretty much all calls were like that.

I worked with HP once at an internship like 15 years ago…I still avoid them because of the shitty experience.
