I've recently been experiencing some crashes where my desktop seems to overheat and then turns off... I can feel the heat coming out off it and even if I click the on button it won't turn on... I have to wait until it is able to be turned on... I think this is being caused by my GPU (MSI GTX 970 Twin Frozr V) because it's cooling system (which is suposed to be smart) doesn't turn on therefore when I'm gaming it starts to overheat.... I donno if there is anyway to fix it, or if it is a common thing... But it could also be the PSU (it has 900w I don't know it's name)...
