I just got back from a 3-day trip and my PC won't boot up at all. It powers on, but that's about it. I already checked if the GPU might be the issue, but it seems to be fine. Any suggestions on what I can do next?

Check for any debug LEDs or error codes on your motherboard. If you haven't already, try clearing the CMOS: unplug the power, remove the battery for a minute, then put it back and reconnect. That might reset some settings and help you boot up again.
Can you access the BIOS or UEFI menu at all? That could give us some clues about what's wrong.
Unfortunately, I can't get into BIOS either.
Have you tried connecting your PC to an external monitor? Sometimes the display can be the culprit, and switching it up can help rule that out.
I did try that, but still no response. I even replaced the CMOS battery and changed the HDMI cable, so that's not the issue.

I replaced the CMOS already and have tried alternative monitors and cables, but no luck.
