Help me, I just cleaned my PC, but after putting it back together it still won’t turn on (no fans spinning at all).
My PSU is definitely on and connected to a power source, front panel connectors are correctly attached (especially the power switch) and plugged into the right slots, ATX 24 and CPU cable are properly connected and plugged in to the correct slots, GPU/CPU connections are secure, RAM sticks are dimmd, and the motherboard is firmly installed with all standoffs aligned.
This is really good, I even have schoolwork ahead of me.

Initially it's important to verify that no pins in the connectors are pushing outward onto the cable side. A budget-friendly tester could be useful for confirming this. If your environment is likely to have static discharge, did you wear a bracelet?

Regarding the area I was cleaning and reassembling my PC, I was outside my house, using a plastic table, and had an electric fan nearby. I also take out metal objects every half hour to release electricity from my body.

For my power supply, if you're suggesting that my PSU is dead, that's unusual for me. Because the day before I decided to clean my PC, my PSU didn't show any signs of failing beforehand—like sudden shutdowns, BSODs, burning smells, or noises from the PSU itself while I was still using my computer. I plan to try a tester if one is available.

About the "pins in the connectors," what were you asking? If you meant motherboard pins, I can't really say for sure due to the many of them. But if you meant the pins for connecting essential cables from the PSU to my motherboard, then none of them appeared bent.

I'm sorry, I missed including that detail. To clarify, I was also using other devices such as my smartphone, a flashlight, and frequently relying on a phone charger since my electric Air duster would deplete its battery while I worked on my PC.

The pins in the connectors for items such as 24-pin or CPU power are designed to snap into place when pushed into the connector. Occasionally, they may push back (wire side) and fail to establish the connection. This isn't common but can be a simple method to overlook a minor problem that needs fixing.

I verified the CPU and ATX cable connections thoroughly, re-settled it properly, and applied additional pressure during installation.
