I have read about this kind of errors on the forum, and seems like mine is not caused by RAM -memtest run all last night without problem-. I formatted to install a clean system, but it took not too much time to the computer to sudenly reboot. Event Viewer indicated , again, 0x1000000a, with the same parameters the other time. I have try to read the minidump file in the ways you commented on he forum, but it is really hard, the only thing I figured out it seems to be related to ntoskrnl.exe Here you have the minidump file and the log txt I made following the steps on the forum. Thanks all for your attention.
