No beep and no video output of any kind. With or without RAM. Without RAM the power LED flashes 3 times then waits a bit then flashes 3 times again. With RAM it's on constantly until it and the fan go off.
I tried recovery instructions, but I'm getting no video output so I can't do anything at that menu. It does stop rebooting itself when I start it that way.
When I start it normally the LED and fan come on then go off and come back on after a little bit. When I hold the power button down to turn it on the led and fan come on after about 3 seconds and stay on. I have 2 monitors connected one via HDMI and the other via Display port. I've tried other HDMI displays as well with no luck.
Edit: I just thought to go back and plug headphones in and with RAM no beeping, but without it I get 3 beeps as the LED flashes then a pause then three more beeps/flashes and that repeats.
