So the other day I took apart some of the bits in my pc, just to do regular mantainence, cleaning out dust, making sure everything is properly secured, applying some fresh thermal paste carefully to the cpu. I switched my gpu to a new pci slot on my motherboard. Ever since then, my computer will shut down as soon as it goes under any gpu load. I have run cpu tests with no problem, as well as ram tests. It gives no errors, and no warnings, just goes black and crashes, then the gpu fans kick on extremely high. I have tried clean installing the drivers, clean installing windows, have made sure the card is secured fully in place, but nothing is fixing the problem. Any thoughts? System specs are as follows: Asus Rog STRIX 1070 8gb, Intel i7 4790k, 16 gb ddr3
