I recently built a gaming computer and for the last few days the graphics card hasn't been working correctly, when playing games it would go to a black screen and the monitor would turn off and now the monitor wont turn on at all. I connected a HDMI cable from the PC to a TV and am now using it that way but whenever I go to play a game it says the drivers are out of date and all that. It won't tell me what version or anything I have and I can't update the drivers to a more recent one. I typed dxdiag into the run thing and it says Standard VGA Graphics Adapter and nothing under the manufacturer
