Hey everyone, I'm in need of some help figuring out what's wrong with my PC. Here's the setup I have: an ASUS B550M-K motherboard, Ryzen 5 5600 CPU, 2 RAM sticks, and a Radeon RX 6600 GPU. My system was running perfectly for three years, but suddenly it won't boot at all.
Just yesterday, it did boot, but neither my keyboard nor mouse worked. Now, it won't boot up anymore. Currently, the fans are running and remain on without any restart loop, but there's a solid orange light on the motherboard, and I'm not getting any display. Interestingly, the GPU fan isn't spinning either, but the USB ports are powered since I can charge my phone, yet my keyboard and mouse don't light up.
Here's what I've already tried:
- Swapping and cleaning the RAM
- Clearing the CMOS
- Reseating the CPU with fresh thermal paste
- Checking the PSU cables
- Reseating and cleaning the GPU port
- Attempted to boot with no RAM installed
Nothing seems to work. Do you think this is an issue with the motherboard, power supply, or something else entirely? Thanks in advance for any assistance!

The solid orange light on the motherboard often indicates a problem, but it can mean different things depending on the model. I'd recommend checking the motherboard manual for what that specific light means. Also, make sure the RAM is seated correctly; sometimes it can come loose.

I checked the manual, and it didn't specify anything about the LED. As for the RAM, I've tried every possible configuration, but nothing changed.
