The C7SIM-Q motherboard with Intel Core i5-750 does not show pictures on the DVI and the VGA D-sub connector. Also, the board has a missing VGA beep (1+8 beep). Is the board defective?
No, the board is not defective. Actually if you would like to use the on-board graphics headers, you need to have a CPU with graphics support (iGfx). Your CPU does not support graphics like Core i5-750. Either choose, for example, Core I5 CPU with graphics support like Core I5 680 or put an additional graphics card in the PCI-E x16 slot of the board.
