Replace with new PS3 and discontinue trying to use the older models that need thermal paste. They overheat because they use so much power 2 or 3 times more than a superslim. Better yet you should have preordered the new PS4 before they were sold out of release date delivery models
Yellow Light of Death
The "Yellow Light of Death" or YLOD is the common phrase people use to describe the following sequence when they try to turn on their PS3:
The sequence above may vary a bit but you do see the flashing yellow light (sometimes shows up as orange) that normally you would not see when operating your PS3. The YLOD is a general hardware fault that can mean a lot of things. However, one of the problems is cracked solder that leads the PS3 to think one of its internal chips is not connected or is broken somehow. Cracked solder can happen when the chips get too hot (RSX most likely) and leads the motherboard to start bending, which may crack the solder. Changing the power supply (lower the average wattage going to the chips to lower the heat) and better thermal compound (heat dissipates faster to the heatsink) may prevent this error from occurring. However, if your PS3 has already had the YLOD, then you can reflow your motherboard every few months to keep it working (but it is not a permanent fix as the YLOD usually comes back).
