I just turned on my computer, and it made a really loud noise, almost like something was stuck in a fan. I also smelled something burning right away. I checked all the fans with compressed air, and they seem fine, but my PC won't start now. What should I do?

Make sure to check the power on signal connection to the motherboard, as that's crucial! If you have a PSU tester, use it. A visual inspection of the motherboard is also key—look for any blown or bulging components. And if you have spares, testing with a different motherboard or CPU might help narrow things down.
Sounds like you might have a popped capacitor, especially in your power supply. The first thing you should do is swap in a known working power supply to see if that solves the problem. It's a good way to check for further damage, too.
Furthermore, can you let us know the brand and wattage of your power supply? Also, what CPU and GPU are you using? It could give more clues. Sometimes the brand can point to issues, especially with lesser-known ones.
Before you switch out the power supply, I'd take a closer look at what's happening. Can you see any burn marks on your motherboard? If not, that could save you from too much hassle.
It might help to upload some pictures of your motherboard and the power supply connections. Also, check near the GPU for any issues. It's a good idea to give everyone a clear view to better diagnose the problem.
