So you are saying that the error comes from a bios errata (and don't know what microdode is), and the fix is to update bios? An “errate” is what Intel calls an error or defect in its hardware, as far as I know. Microcode is sort of a “firmware” running in a CPU. For example, the TSX feature in Haswells (which was one of the reasons why I chose my particular CPU in the first place, grrr) was found to have a bug, so Intel produced a microcode update that would simply disable the relevant set of instructions. no, possibly from a CPU errata and a bios update might bring in the microcode update that works around that. I see, thanks for clarifying that. So looks like not too many options, either try to update the bios and/or replace the CPU. Not necessarily. The first search hit (“linux update microcode”) brought me to ¹, another to ². The latter led me to finding sys-apps/microcode-ctl, which might do what you need. ¹ https://wiki.archlinux.org/index.php/Microcode ² http://www.linux-mag.com/id/723/ Thank you very much for the explanations. Very clear indeed. I'm gonna work around with this microcode stuff and see if that helps. I appreciated you reply!

So looks like not too many options, either try to update the bios and/or replace the CPU. I really appreciated you replys and time. Thanks!, Sebas There's a few things you can try. 1. Go in the bios menu and reset it to safe defaults or similar setting. If that don't work play with the settings, especially memory settings (try lowering the frequency). 2. If the motherboard is dirty, clean it real good. This may sound crazy but I've had success spray washing it with a hose and drying it on a warm oven. 3. Flash the bios with the latest version. 4. If you have a soldering iron and junk parts laying around replace any blown capacitors on the board. The first one I already try with no luck. Now you mention it, it is a little dusty the motherboard... and looking carefully I think it could be some capacitors may are some blow (but not for sure). Thank you very much for the tips, I'll try them all!
