My PC boots for a few minutes and shuts down, if I press the power button again it would flash and then shut down immediately. It all started when I foolishly cleaned my CPU fan under running water and failed to push the boxed push pins and stuck them with super glue which could have covered a teeny tiny chip near the pin area, I installed a new power supply but it still didn't work. The heat sink is working but I doubt its performance had upgraded. It might not be an overheat issue as the CPU usage was not full.
