I'm using Memtest myself as a point of reference to keep in mind, but de facto RAM could be 100% ok after it failed and it could be borked after it passed Memtest, let alone that one of the computers I tested always failed when using Memtest from Ubuntu repositories and always passed Memtest of the same version, when using a Memtest live CD, both after shut down and disconnecting the PC from the mains. There are tons of other possibilities that could cause issues, even clearing CMOS _without_ replacing the battery could solve a lot of issues. Just running Memtest gains absolutely nothing. Running Memtest in combination with other tests and actions is very helpful. Smartctl is not perfect, but another link in the chain, even unplugging SATA cables and connecting them again is important and so on and so forth... Just running one test, especially the free as in beer Memtest release gains absolutely nothing, at least taking a look at /var/log, journalctl and Co in combination with software testing hardware and remounting, cleaning, etc. should be done. More experienced users could use coolant spray etc. ... Always keep in mind that measuring a faulty system by software running on this system is fishy. A repair shop always tests equipment with other equipment galvanically isolated from the mains. -- Guerilla Open Access Manifesto: https://archive.org/stream/GuerillaOpenAccessManifesto/Goamjuly2008_djvu.txt -- Lubuntu-users mailing list Lubuntu-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/lubuntu-users
