Story time: I’ve had my work laptop replaced three times in the past two years because of persistent crashes under load. We tried replacing a lot of stuff, uninstalled all kinds of software etc., nothing helped. Turns out they’d remotely installed some utility about five years ago that controls fan speeds. That has been installed on each new machine because it was in my profile. When I checked, I found out that this thing hadn’t been updated in three years and was likely not compatible with my current hardware. Uninstalled it, never had problems since. So yeah, that was fun. At least I got a new laptop out of it.
