If your going to use the on-board video for this motherboard, make sure you check on the contact point of every peripherals like the memory chip. It should be cleaned using a standard eraser (use in erasing pencil marks), Before inserting it to the memory slots.

Do a repetitive insertion between the memory and the slots severals times until you boot up the pc. I would suggest you disconnect the Hard drive from its power source and from the motherboard while doing this procedure.
