PC suddenly rebooted with no display output

[Siguardius]

I was watching some videos while my PC suddenly shut down and rebooted with no display output. Checked HDMI and DP output from graphics card, switched to internal GPU, even checked. USB-C output and there's nothing. Switched monitors. Nothing. Everything lights up properly, GPU starts spinning, all fans are working, keyboard and mouse light up. The only issue is no display output. I'm not really asking, but more looking for confirmation that my motherboard died on me. Or maybe you have some other ideas?
