So I have a Radeon HD 7700 and starting today when I try to turn on my PC with the GPU connected through its DVI, the monitor shuts down and the keyboard/mouse become unresponsive. However, when I instead boot up the PC with my motherboards HDMI it turns on correctly. I think it's the GPU thats causing the issue but when I reconnect the DVI after starting up, nothings wrong and everything works fine. Anyone know what could be causing the issue?
