I was cleaning the computer fully so I dismantled every part of the PC and reinstalled everything back to how it was. Everything seems fine but the CPU Cooler and motherboard metals are not heating up. Huge performance drop I'm encountering. I'm assuming it has something to do when I reinstalled the power connectors of the power supply to the motherboard where now, the motherboard and CPU cooler are not heating up as I feel the ribs of it. How can I fix this?
