I've just installed my newly purchased Intel DX58OG desktop board. Whenever I power on the system, the post 80h code "91" will be displayed. Considering the list of status codes, it seems the board stops the post process when "disabling the keyboard". However, I've connected the USB keyboard (in fact, I've tried two different USB keyboards) with every possible USB port to see if it remedies the situation. It won't. My guess is that black screen results in the board not being able to go beyond code 91, thus preventing the graphics card from being initialized.
Is there anything I can do to the video output appear? I'm pretty clueless right now. :/
Any help will be greatly appreciated!
