I recently ran DDU in safe mode to perform a clean driver install for some troubleshooting. After my computer restarted, I was shocked to find that there was no display output at all. My system boots up, peripherals light up, and there are no error codes showing, but my monitors just say "no signal found." I can't even see the BIOS or the motherboard logo – absolutely nothing. I've tried reseating the RAM, CPU, GPU, and CMOS battery, changing cables, and switching ports. Even trying a different GPU didn't change anything. The odd part is, I can hear the Windows boot sound, but still no video output. I'm at a loss here and could really use some advice!

It sounds like your system is having a tough time with the display. Have you checked if your monitor is functioning properly? You could try connecting it to a different device to see if there's an issue there. Also, make sure the cables are securely connected. Sometimes, a faulty cable can cause that "no signal" message.
Given your setup, it might be worth resetting your BIOS. You can do this by removing the CMOS battery, waiting a few minutes, and then putting it back in. It could help resolve any configuration issues that might have cropped up after the DDU process.
Tried resetting the BIOS, but still no luck.
Yeah, I connected the monitor to another PC, and it works fine. So I guess it’s not the monitor or the cable.
