PC only powers on for half a second?

Troubleshooting

Hello, today I encountered a pretty bad problem with my custom desktop pc. I've had it for 2 years, and it's been working consistently fine the entire time. Today I decided to remove some parts to clean, and now it only turns on for half a second before stopping. The parts I removed was my gpu, ram, and a case fan. I know the gpu and ram are fine because I plugged them into another build and they function properly. When I try to turn on the pc, my gpu LEDs light up and all the fans spin for half a second, then it all stops. The lights and fan only start up after I turn the psu switch off and on. Weirdly, the mobo LEDs that are always on still work, so I'm not sure where the problem is coming from. Maybe unplugging the fan did something, but I'm entirely unsure. Any ideas would be greatly, greatly appreciated!

Check your standoffs or the back of your motherboard for any shorts.

Should I remove the mobo from my case to check? It's somewhat covered by the case, and I need to check the back of the mobo, right?

If you have the time, rebuild outside of the case and see if the issue remains. But yes, you'd probably have to remove the mobo.

I'll make sure to do that in the morning. Thank you for the suggestion, I've been stumped on this for an hour
