Ok so, for some reason my graphics card gets super hot that i cant even touch it! it burns so bad, I do have an older xfx 850w power supply could it be the power supply that i bought of ebay for dirt cheap? I did clean out the graphics card, and replaced the thermal paste! but i can't just figure it out! the graphics card makes a buzzing sound that i haven't think i heard before, the graphics card is an xfgx r9 280x. And the graphics only gets hot while in games.
