I have been building my pc and when i start up my computer i get nothing on my monitor. I have made sure every thing is in place, moved the memory, cleared the RTC ram, and made checked the DVI and VGA cables. I have a Asus p8h61m-le motherboard, intel core i5-3450 1155 processor, and a G.skill DDR3 1333 memory.if it helps any the speaker is beeping 4 short times. It seems like a motherboard issue. Any info will help.
