I have a prebuilt PC that I got from my dad, and after a few years, I decided to open it up to clean out the dust. I didn't have a blower, so I just used a dry cloth. After cleaning, I noticed that the fan was making strange noises, which I thought might be caused by something like a screw or a wire getting in the way. After a minute, the PC completely shut down. How can I determine if my power supply is the issue? What's the best way to test it?

Check out the paperclip test online. It's a simple way to see if your power supply is still working without needing another unit.
There are devices out there you can plug your power supply into for testing. If you don’t have one, using another PSU or PC is the way to go to isolate the issue.
To check if your power supply is broken, you'll need a different power supply to test it out. It's pretty unlikely that you damaged it just by dusting with a cloth. Can you tell us more about where you cleaned and the exact noises the fan is making?
Wiping everything inside could potentially damage small components or create static. It’s best to just clean the case parts and fan blades. It's unlikely that you harmed the PSU; maybe you just accidentally unplugged some cables. Those front panel connectors are pretty delicate.
