My rx 480 8gb, which I had running under a pretty high overclock with a cpu aio to cool it died yesterday. The day it died, the GPU had been throwing up all sorts of artifacting, even when I dialed back the overclocks and ran with little overvolting. Later, when I was running 3dmark to try to figure out if it was stable, my computer hard crashed and the GPU stopped outputting. In addition to not outputting, it wasn't recognized by windows, even when I uninstalled and reinstalled drivers. Today I fully removed the card, ran the heatgun over it for 5 minutes or so, then when that didn't work, I tried again for 10 minutes with no success. I'm starting to wonder if the PCI slot may have been damaged due to too much power being drawn through it, as the GPU die didn't heat up at all after I reinstalled and tried to run the card today. If the PCI slot is fried rather than the GPU, would it be fixeable using a heatgun, even if temporarily?
