I've been struggling with this problem for a week and a half: my PC isn't showing any display, and neither my keyboard nor mouse seem to power on. I've already tried a bunch of fixes, like reseating the RAM and GPU, clearing the CMOS, and even buying a new motherboard. I'm at my wit's end here trying to figure out what's wrong!

You might want to check if your motherboard has a debug LED to help diagnose the issue. If not, try booting with just the essential components—remove all drives and peripherals, and test each RAM stick individually in different slots. If that doesn’t work, consider flashing your BIOS, depending on what those debug LEDs indicate.
What are your specs? Did the PC just suddenly shut down, or was it off properly before the issue? Does anything power on at all?
I have an RTX 4060 Ti, an ASUS Prime B650M-A AX6 II, and a Ryzen 7 7700. I turned it off and left for a few hours, and when I got back, it wouldn’t turn on. The fans and RAM RGB light up, and the fans spin, but that’s it.
