  6. oBGi2P2sUIPIH3GQ

    • Loosen the 5 screws (4mm, Phillips #1) that secure the CPU Heat Sink to the motherboard.

    • These screws are held in place by a washer so you should not be able to completely remove the screws.

    My fifth screw, (the one towards the bottom), won't unscrew. Anybody that can help?
