So I had a bad experience with my laptop when cleaning out the vent. I had to remove the heatsink to clean it out, but then the computer turned off constantly. I opened it up again and I applied thermal paste to where I saw old thermal paste (on the CPU) but, now the computer stays on but it turns off more often then before I cleaned out the vent. should I apply thermal paste to the "gpu" area? It doesn't have paste (from what I can tell) It just has some kind of thermal "sticky tack" "gum" looking thing.
Note: The thermal paste I applied to the CPU was like 4+ years old. Would that be a problem?
