Just thought I'd share the troubleshooting I did recently rather than asking a question as usual. I found a lot of topics about this but usually people ended up not responding anymore or had different solutions.

Error type: PC is not booting anymore. The QLED of my Asus TUF x570 Pro Gaming (and whatever fancy super mega plus tags it has additionally) was showing a constant white light (VGA LED). Monitors showed no display.

Solutions I found and tried and that failed:
  • Check cables (duh)
  • CMOS reset
  • Used a different power source
  • Used a different monitor
  • Used different connectors for the monitors
  • Used a different graphics card
  • Used a different PCI slot
  • Used a different PSU
  • Tried different RAM slots with just 1 stick
  • Used a different mainboard
Actual solution: The CPU (Ryzen 3900XT) was broken. Replaced it and everything worked like a charm again. This was pretty much the last thing I suspected, but here we are. Thought I'd share this so that maybe some people stumble upon it when searching for this issue. Not the best first impression I got for AMD CPUs...

Which is the very first thing anyone would suspect when seeing a VGA LED. Most of the topics I found also revolved around completely other things and the CPU as a possibility (and solution) is only mentioned in one. Hence I thought adding a topic putting this on the radar might be helpful for some as this might not be the most intuitive culprit.
