My monitor is an asus vg248qe for reference.

I was recently trying to connect my cintiq 22hd to my desktop by plugging it in, I go upstairs for a bit to find a cable and I come back down to see my conputer in sleep mode, or rather my monitor. I turn off the computer and turn it on only to find my monitor displays "DVI no signal" when it was working fine literally 30 minutes ago.

I tried replugging all of the wires, it's definitely in the correct inputs and I opened up my build to see a memory card popped out- I put it back in and STILL NOTHING? I'm at a loss here can anyone help?
