I also have the AMD of eight cores, and I do not know why I gave that problem by that date exactly, although with Windows 8, it seemed that I did not load the icon of the antivirus and then the blue screen, later I finished formatting the pc, then I It will happen again when reinstalling. I do not know if it really is the antivirus or my system and other software, but after having found this, I will be attentive on the subject. Of course a good forum that I had not seen before. Regards !!!
