I was thinking it was BCS of the gpu, I will buy new one in December and thank you for the info.The mobo's GPU is dying. You can buy a dicrete 750ti and plug your monitor there.
What is the make and model of your PSU?
The motherboard is used I bought it form another guy. So that makes sense that the gpu is dying. The psu is working fine, it's good but not the best, Fsp group Inc. Forton/source model no: FSP400-60GHN(85) 80plus BR (hope it helps)Before you buy, if possible, borrow from a friend to confirm that this is the case.
Also, please write your make and model of your PSU.
