Hello guys. Thank you for viewing this.
I have my PC hooked to a Yamaha RX A700 via HDMI from a Asus Xonar Deluxe 1.3 and this is hooked to a GTX 470. The only way I got this set up to work is by using a second monitor and by selecting RX700 in screen resolution as the second monitor.
Today I got on the pc (left it on since I last used it) and plugged in my A/V receiver (I unplug the power every night) and my GTX 470 no longer recognizes a second monitor.
Its unbelievable because nothing was done besides unplugging the A/V receiver power since I last used it. I doubt even the cables have moved since it last worked (I have since triple checked every connection).
I have uninstalled and re-installed drivers for both the GTX 470 and Asus Xonar and have done a system restore and it hasn't worked.
Any advice or suggestions would be immensely appreciated as I live and breathe through this machine and no audio will be devastating.
I am even willing to go so far as offering a reward to the person who is able to help me through this. Thank you for your time.
