My computer won't turn on. There was a brief power outage while the PC was powered up, and now it doesn't start. When I press the power button, nothing happens. The motherboard RGB is still active, so it seems the issue isn't with the power supply. I also tried using a different switch, but that didn't help. Recently, something unusual occurs every time I turn on the PC. Pressing the power button causes it to turn on, but then the fans stop and it loses power completely. After a short time, it restarts as if nothing happened. I was able to live with this before, but now it doesn't work at all—no fans, no boot, just the RGB lighting. Please help.

It's a brief. If that brownout occurred precisely when you powered on your PC; in simple terms: YOUR
<Mod Edit>
The short shut off and restart was likely because the BIOS detected an issue and restarted. However, your description suggests it powers off shortly after turning on, indicating a possible short or discharge. Now that you mention it won't power on at all, it could mean an internal failure, insufficient power, or another problem beyond the motherboard. I’d recommend testing it with a breadboard, running it through various scenarios, or performing a power cycle—turn off the PC, unplug it, remove the CMOS battery, and discharge it before reinserting. Then try again; if it still doesn’t work, it might have been an overvoltage event during that brief brownout. Don’t worry, this can happen.
