As the title said,my pc was all good before that then i tried installing ny new gpu,but sadly the gpu wont show any display,tried everything,changing the settings in the bios, but the after a few tries of tturning on and off the cpu,my pc wont post anymore, tried reseating everything again thinking that something just got loose, then it caught my attention that the atx_12v power connecyor in the board was heating up when im trying to turn on the pc,any tips guys?
