I recently encountered an issue with my PC that has me puzzled. Here are my specs:
- MSI B650 AM5 micro ATX motherboard
- Ryzen 5 7600 CPU
- RX 6650 XT GPU
- 2x8GB Kingston Fury RAM
- NVMe Samsung 990 1TB SSD
- Deepcool PF500 PSU
This morning, when I tried to power up my PC, it only stayed on for about 5 seconds before shutting down. My monitors didn't turn on, and the keyboard didn't light up at all. I attempted to turn it on multiple times, but it kept behaving the same way.
So far, I've reseated my RAM and tested each stick in different slots. I also unplugged all peripherals. While doing this, the PC didn't turn off, but only the fans were running, and the CPU debug LED on the motherboard stayed lit. I even reset the BIOS, but the RAM LED blinked a couple of times and returned to the same state.
Just to rule things out, I tried powering it on without the GPU, but there was no change. I haven't overclocked the system at all. Interestingly, I noticed some screen flickering yesterday, but that disappeared quickly.
I'm desperate for help as my midterms are coming up, and I need my PC fixed pronto! Could any of my components be unreliable?

It sounds like a classic case of a failing power supply to me. If the fan spins but the system won’t boot or display anything, that could indicate the PSU isn’t delivering adequate power. You mentioned the motherboard debug LED is on, which is often a sign of a CPU or power issue. Have you tried using a different power supply? Sometimes a simple swap can determine if that’s the issue.
I’d guess it could also be a faulty CPU. Did you know your Ryzen 5 7600 has an integrated GPU? It might be worth connecting your monitor directly to the motherboard to see if you get a display, even if it didn’t work before. Sometimes the integrated graphics can help troubleshoot issues like this.
Good point! But you also want to check if this specific CPU is known for any issues. Some models can just die unexpectedly even with normal use.
That's true, but make sure to check your connection cables too. A loose cable can also cause similar symptoms. It’s an easy fix if that’s the case!
