Hello everyone,
I wanted to remove the drivers using DDU. When I began using DDU, I was told to run Windows in safe mode, which I did. But I didn’t realize I had encountered issues accessing the BIOS before (when I powered on the PC, I saw only a black screen after logging in, and pressing DEL didn’t help). I’ve accepted that situation, but now that I’m back in safe mode, I’m still facing a black screen. I followed all possible suggestions without success, so I tried flashing the BIOS via the flash BIOS button (just let me know why I don’t remember). The flash worked, but the screen remains black with no output. Initially, the EZ debug LED was lit to start the boot process, but now when I connect one RAM slot in A2 and power on, the LED is off, yet the screen still appears black. I’ve tested various monitors, all ports, and cleared CMOS, but nothing has changed.

Specs:
MSI MAG B550 TOMAHAWK
R5 5600X
XFX RX 580 GTR-S Black Edition 8GB
Enermax NAXN ENP550AWT 550W
G.Skill Trident Z 2 x 8 GB DDR4 2133 MHz

If you connect your monitor directly to the motherboard's video output, it may affect display functionality. Check for any audible signals or status indicators that could signal issues.

Sorry to hear your CPU lacks built-in graphics. It seems there are no beeps or status messages, just a black screen. The monitor's LED stays on, but it doesn't display errors like "No signal" or "Cable not connected."

Another GPU might not be detected by Windows

It seems the best approach is to try and resolve this issue on my own.

Are you sure you need a USB stick to retrieve your motherboard BIOS by looking up your manufacturer on YouTube?

If you're referring to refreshing the latest bios, you've already done it using the bios flash button on the back of your motherboard.

I connected another CPU and it didn't show anything. Probably added something.

So, running in safe mode, black screen appears, BIOS update is happening, same issue. Debug disappeared with low RAM stick, seems like a Windows problem? Have you checked your OS drive? Did you unplug and plug it back in? Have you tried a full power-down, turning off the PSU for over 10 minutes? It could be a bricked motherboard, but I'm not sure. Does your motherboard still show debug lights when cycling them?

I replaced the os drive and everything seems fine. I repositioned all components. I didn’t leave the power off for too long, I’ll give it another try. The debug LEDs appear to function correctly—lights on the CPU briefly, then off, VGA light pulses briefly, then off, and similar behavior during boot. Only the RAM LED skips.
