after yesterday's thunderstorm, my gpu got fried. I've tried the wash technique, didn't work. after a 2nd go with a heat gun, this time for a minute on the cpu, it was stable into windows but i was stuck at 800x600. this is what gpu-z saw, it detected as a basic display, could not read the gpu details. i thus proceeded to install drivers and that's when the gpu lost power again and would not show up despite reseating and several reboots. its faulty so what do i look for and how do i fix this. help please?
