It is not a package that runs under Linux. You stick the .iso on a small flash drive and boot it directly. The first thing to try in these situations is always to reseat all connectors, and if that doesn't work, try another slot. > On Sun, Nov 5, 2017 at 6:09 PM, Robert Krawitz <[email protected]> wrote: > >> On Sun, 5 Nov 2017 17:52:45 -0500, Michael wrote: >> > good thought yet all returned ok >> >> You could try memtest86 (which is much more thorough -- it's a mini-OS >> of its own that needs to be booted). >> >> I would certainly not be surprised if it's thermal in nature.
