After going through the BIOS multiple times with a microscope and turning off any and all settings that pertain to OCing (which some are on by default so you gotta keep your eyes peeled) I "think" my problem might be cured. I will stress it with a good bit of GTA V which was causing me tons of BSOD's last week. So far though I have not gotten any playing BF4 or FO4 over the past couple of days. Cross your fingers!
EDIT : My bad, forget that now a fresh win10 1511 install set the power management as "performance" instead of "balanced"
Dear god, that win10 1511 is the worst windows version i ever had to deal with.. So many issues had to reinstall this thing so many time. Even windows vista was less annoying than this crap 1511 version... Hope somes proper update are going to come soon -_-"
