I recently replaced my computer's power supply unit (PSU) after the old one blew out. Initially, it powered on, but I noticed only one fan was working. I called a PC repair shop and they advised me to check all the connections and make sure the fans are plugged in properly. I did that, but now my PC won't turn on at all. I bought the new PSU with birthday money and I did want to do this repair myself because I can't afford a repair shop. What should I do now?

Double-check the rocker switch at the back of the power supply. It needs to be in the 'on' position (the 'I' symbol). If it’s accidentally flipped to 'off' ('O'), your PC won’t power up.
First off, make sure you used the new power connectors that came with the PSU. Sometimes using old connectors can cause issues if they're not compatible. If you did, then it might be a different problem.
I definitely used the new connectors that came with it.
I've checked that, and it's definitely in the correct position, but still nothing happens.
