Dear Sir,
Thank you for your kindly mail and inquiry. About the issue you mentioned, due to there are many VGA card in the market, we might recommend user to test the VGA card with your motherboard before you buy it to avoid H/W compatible problem. And sometimes because high performance VGA cards requires additional power input, so please make sure that your power supply unit fits the power requirement.
In addition, please kindly notice that we would not test other brand VGA card on our motherboard, we could only guarantee GIGABYTE VGA card can work properly on our motherboard. If your problem still remains, we suggest you to test with GIGABYTE VGA card and see if it is compatible problem or motherboard issue.
