So I can tell that the RAM is all right on this desktop PC box, right?
Most likely the main memory is _not_ defect. However, when passing the memtest it's without guarantee that the RAM is ok and if there would have been errors, it also wouldn't necessarily mean that the RAM is broken. Memtest isn't perfect. But since we are talking about "Voodoo", have you checked, if your power supply is able to handle the worst case scenario? Have you replaced the battery? Power supply and the battery unlikely are the culprits either, but both could cause "Voodoo" too. I suspect that it's a software issue or unlikely a very wicked hardware issue. Have you checked the homepage of your mobo regarding BIOS updates (or whatever the "BIOS" is called nowadays). Are there changelogs that ever mentioned Linux incompatibilities? The very last thing I would do, is to care about strange "Voodoo". I would test Arch's Linux LTS, downgrade systemd and similar. Most likely it's a user issue, or a complete incompatibility to Linux of some hardware component. I returned several times hardware that was mentioned by the vendors by Linux communities as Linux compatible and not seldom it put out, that there was one revision, chipset nobody cared about, neither the communities, nor the vendors or nobody did use all features of the hardware. Backup your current install and make a clean new install. Replace the default kernel with https://www.archlinux.org/packages/core/x86_64/linux-lts/ or with linux-rt-lts from the Arch Audio repository or from AUR, since it's 3.10..., don't worry about the Rt-patch, when instlling it just for testing purpose.
