I'm having an issue where there's no video output after my PC unexpectedly shut down. Everything else seems to be functioning normally; I just can't get any picture on the screen. I've tried using both my 970 and 2060 graphics cards, but neither worked, and both monitors just show a 'no signal' message. I've reseated the CPU and RAM, as well as checked every cable from the power supply on both ends. The red and yellow debug LEDs are illuminated, but they've been on before without issues. For context, I'm using a B850 Tomahawk motherboard. I've also attempted to clear the CMOS with the built-in button, but that didn't help either. Any suggestions?

It might be worth checking the video cable connecting your GPU to the monitor. You mentioned both monitors worked previously—could you try a different cable if you have one? If you’ve reseated everything and the cables are fine, we might be looking at something else.
Have you given the display some time to come up? Sometimes it can take a little while, just making sure you're not turning off the system too soon. I’d suggest waiting at least 15 minutes before assuming the worst.
