Opening the PS3 Case
Unplug the PS3 power supply and any audio and video cables connected to the PS3. Put the PS3 on a clean cloth.
Lift off the hard drive door on the side of the PS3. Take the #1 Phillips screwdriver and remove the blue HDD screw. Put the screw aside.
Slide the hard drive towards the front and pull it straight out of the PS3. Put the hard drive down on the clean cloth.
Remove the warranty sticker at the top of the open space where the hard drive was taken out of. Unscrew the rubber foot from inside and put it aside.
Slide the top of the PS3 to the left to expose other screws. Remove all the screws that have an arrow placed next to it. Put the screws aside.
Lift the top of the PS3 off from the back until it stops. Turn the PS3 around so that the components are facing you. Remove the ribbon cables connected to the memory card readers if using the first generation PS3. Take the top off and put it aside.
Lift up the Blu-ray drive and remove the power cord and data cables attached to the Blu-ray drive by pulling them straight out. Put the Blu-ray drive aside.
Turn the PS3 sideways and remove the screws holding the WiFi antenna. Remove the ribbon cables attached to the WiFi antenna by pulling them straight out. Put the WiFi antenna aside.
Remove the two connectors attached to the front and back of the power supply. Remove the screws and remove the power supply.
Remove the power eject switch by removing the ribbon cable and removing the screws holding it to the circuit board. Put the switch aside.
Remove the screws attached to the top case that have arrows noted by them. Turn the PS3 over and remove the protective casing. Put the PS3 back down.
Remove the plastic tabs on the case to release the back side of the PS3. Put the back side aside.
Remove the connector attached to the fan and remove the screws holding the fan to the circuit boards. Pull the fan up and put it aside.
Disconnect the battery by pulling out the cables attached to it. Remove the screws holding the hard drive bay in position. Take the hard drive bay out and place it aside.

Repairing the CPU and GPU
Locate the two gray plastic squares near the middle of the circuit board which are the CPU and the GPU chips.
Take the heat gun and adjust the temperature between 300 and 500 degrees F. Heat both sides of the board with a swirling motion and a back and forth motioo for less than a minute on each side. Put the top section dpwn on the cloth and heat around the CPU and GPU chips for five to six minutes.
Reduce the heat to 80 degrees and continue to heat around the CPU and GPU for another two to three minutes
Let the circuit board completely cool down. Reapply some thermal compound to the top of the CPU and GPU and smooth it out with a credit card.
