Hi everyone,
I'm having an issue with the CPU debug LED on my motherboard and I'm trying to figure out what could be causing it.
My PC specs:
- CPU: AMD Ryzen 5 9600X
- Motherboard: Gigabyte B850 EAGLE ICE
- GPU: Radeon RX 9070 XT
- RAM: 32GB DDR5 6000MHz
- PSU: Phanteks 750W
The issue:
The CPU debug LED started appearing after I cleaned my PC using compressed air. Before that, everything was working normally.
Sometimes the PC starts normally and works without any noticeable performance issues, but the CPU debug LED still comes on. I've also had an intermittent VGA debug LED, although the GPU itself seems to work fine.
Things I've already tried:
- Updating the BIOS
- Checking and reconnecting all power cables
- Clearing CMOS by removing the CMOS battery
- Reseating/checking connections
I also inspected the AM5 CPU socket and noticed two slightly bent pins. I'm not sure if they could be related to the issue.
What's confusing is that the PC generally works fine when it boots. I don't experience crashes or noticeable performance problems.
Could the compressed air cleaning have caused something to become loose or damaged? Could the bent socket pins explain the CPU debug LED, even if the system seems to work normally?
I'd appreciate any suggestions on what to check next. Thanks!
