So I just changed my computer's motherboard and when I turn on the computer there's no beep and nothing appears on the monitor. The hard drive, disc drive, cpu fan, and all other fans turn on but there is no beep when I turn it on and nothing on the monitor. Already tried different HDMI and DVI ports and cables and still the same. Checked that everything was connected correctly inside the computer and it is. Please help.
