Some sound coming from inside the computer
I have this problem with the fans inside the cpu. Just lately when I did a shutdown of my computer and the monitor did shut down and so was the computers’ led lights, I notice there was still some sound coming from inside the computer and when I opened up the case, I found out that the CPU fan and the case fans were still running although the computer was already turned off.
The PSU fan was not running yet both the case and cpu fans were still turning!! I tried waiting for it to turn off by its own but it went on for more than 15 minutes. I had to unplug the power cord then tried again the whole process if it will occur but the fans won’t still die down. I had an extra power supply, changed it yet still the same.
I don’t remember having any problems running the computer aside from this one.
