My system turns on, but there is no signal to my monitor.

My PC was left on and when I came back to it, the monitors were all off and the PC was still on, I moved the mouse, but it did not come on. The mouse and keyboard LEDs were also not on. I turned it off and on again and it still all lit up, but no monitor signal. So I unplugged all of the cables except a HDMI and the PSU power and tried again, it did not work. I have tried 4 different monitors, over HDMI, VGA and display port. I the took out the RAM and just tried one stick in all four RAM slots and did this again for the other one. I have also been linked to a trouble shooting thread and did all of the suggested items on that. I have tried using the on board graphics and have tried both of my GPUs separately. My error code on my motherboard shows about 10 different numbers, instead of just one. If I press the MEM OK button, the PC turns itself on and off repeatedly and a little red LED flashes, also my HD LED is flashing yellow and my DRAM and CPU LED are flashing red. I have pressed the reset button on the board and this has done nothing, I have been told to clear the CMOS, but I do not know how to and it is not stated in the book. All of my cables are in and tight and no ends are touching the case. I think this happened a few years ago and I think I fixed it by downloading a BIOS, but I cannot remember. Any help is appreciated. Thank you.
