I had already tried a bit more voltage on the card but no luck. Just tried more voltage in the NB but same happens as well. But I think the problems resides somewhere in there. The card is probably faulty, some electronic component is bad, do you guys think that's possible?
Still, it does work with Ubuntu, testing again now. Can Linux be more tolerant to those kind of electric problems for some reason?
edit: while messing with more values in the BIOS I've noticed that manually setting the PCIE frequency to 100 makes the card exhibit the BSOD every time I login, which happened a couple times to me when it was set to auto (BIOS Default). I wonder if that auto setting is not doing the best job and that's why the card fails.
However. I read it's dangerous to increase this value manually, so at this point I really don't want to put anything at risk.
