Hello, my computer is around three years old. Everything was functioning perfectly until three days ago. That day I just restarted it, but during the boot process it didn’t start. The fans are working, the GPU is active, but there’s no signal on the monitor. I’ve checked the monitor and everything looks fine. I force shut it down and turned it back on a few times, and it booted up. If I had shut it down instead of restarting, everything would have been okay. Today, after a normal shutdown, I still face this issue. All fans are working, RGB and CPU fans are active, but the monitor shows no signal. I tested the keyboard by pressing Caps Lock and Num Lock for the light, but it didn’t respond. In short, my PC isn’t booting properly, though all other components are functioning.

I’ve tried several fixes but the problem persists:
- I have only one RAM stick and cleaned it.
- I removed the CMOS battery, waited 15 minutes, then reinstalled it.
- I pressed the power button briefly to discharge the battery.
- I force started the PC multiple times, but it still won’t boot.

I’m unsure what to do next and really need help because I rely on my PC a lot.

If you reviewed the article, you should identify the phase where the failure happened. What outcome did your bios phase test yield?
