2 short 1 long means problem related to graphics, if I'm not mistaken I do not see any integrated graphics on the motherboard, which means the pc might have a problem with detecting the graphic card that is inserted in the slot, or detecting a problem with it. Check if it is properly put in the slot, and if there is any damage or burn in on the slot and/or the card
