Do you have access to another graphic card to try, so we can determine if it is the motherboard or the card that is at fault?

Can you try the graphic card in another computer to see how it behaves?

i tried it another pc.. that pc has tt500w psu, 3rd gen core i5 - asus b75 with vegnc 8gb ram 1600mhz...
i also changed motherboard from ASUS H81M-E to GB H81M-s2pv..but problem doesn't solve..

If you had a previous (old) graphics card, make sure those drivers are uninstalled.
