I was streaming a video and my computer froze. I turned it off now it starts with no beeps at all and no display. CPU fan is running, GPU fans are running all case fans plugged into the motherboard are working. I have tried plugging the monitor into the internal graphics, different pci port, different card all with no display. Can't get to the bios, monitor doesn't recogise that any signal is being sent. Is the motherboard broken or is it something else?
