Don't know about, "all ISOs being bad," but I do know, that for about the last 5 or 6 months, or maybe even longer, Linux Mint 19 (Sarah) has been locking up on me, or freezing up on me, and the only thing that I can do, to get the HP Notebook to run, or to get it to shut down, or to get it to reboot, is to press and hold, the power button, for a few seconds, until the Notebook shuts off, then I can press the power button to get the Notebook to run. Anyway, I may go to another version of Linux...I used to use Mandriva, and I liked that very much, but of course that's no longer supported, and I also have tried many others, like Ubuntu, Kubuntu, Ultimate (Gamers Edition), even a Linux version of a Media Center, like Microsoft had, where they have a lady, in a video, telling, or showing you, how to set it up, and I liked that version, but that version was mainly designed to operate security cameras, and things like that...Anyway, I have used many versions of Linux, but not sure what version to try using now, and yes, I do run the updates, not a complaint, just an observation...
