So my ps3 fat wasn't working so i changed the thermal paste and put it back together and then a couple of days later i heated it up with a blow dryer because the last time i did it before i changed the thermal paste, it worked but only for an hour, when i press the button the light goes green, yellow then flashes red, idk what else to do and i think the problem might be that I didnt heat up the cpu and gpu before putting on the thermal paste, any suggestions
