No signal between monitor and computer

I weren't sure where to post this, but I think it's software related.
Suddenly when I were gaming, my monitor went black and started displaying "HDMI: No signal". I restarted both computer and monitor, and a few seconds after boot (while viewing desktop) it goes black again and displays "HDMI: No signal" again. I've tried connecting computer to different monitor, same thing happens. I've tried with a diff HDMI cable, same thing happens. I've tried with different input, same thing happens. Because this happens while the programs that executes on startup is executing, I'm thinking it's software related.

Thanks in advance,
Hydor.
