I have a really old computer that suddenly stopped working. At first, it would turn on, but the monitor displayed no signal, and the keyboard and mouse wouldn't light up. Then, it shut itself off. I tried reseating the RAM and even swapped out the graphics card with a spare, which allowed it to stay on, but there was still no signal and the peripherals didn't power on. In the end, I removed everything, unplugged all the cables, and plugged them back in. Now, unfortunately, the computer won't turn on at all. A family member suggested that it might be the power supply because of its age. I'm not experienced with computers, so I'd really appreciate any advice on what to do next!

Yeah, it sounds like the power supply could be problematic. Without a spare to test with, taking it to a repair shop where they can troubleshoot would be a smart move. However, if the PC is working fine for your needs, you might want to avoid the expense of a full replacement.
Make sure you've disconnected the power properly before troubleshooting. If you didn't, you could risk damaging more components. You might want to try the power supply test using a paperclip to jump the pins; it can show if your PSU is at fault.
Given that it's an older PC, I'd suggest the power supply is likely the culprit. If you have access to a different power supply, trying that could help you figure things out quickly. Otherwise, taking it to a repair shop for diagnostics might be a good idea, but since it's old, you might want to consider putting that money toward a new machine instead.
Jumping the power supply with a paperclip can really help. You can easily find tutorials online showing how to do it if you're unsure.
