hi i just bought an asus gtx 680 direct cuii oc card. i installed it and it was great for two days untill it stopped working with multi monitors. i returned it and recieved a replacment. upon installing it i still have the same issue. i am trying to power the monitors through a hdmi and twi dvi cables... does anyone have any suggestions or idea to fix this as i have run out of options... i will be buying new cables tomorrow to hopefully fix the issue.
