hello guys laptop started to make clicking sound once in a while, i cant hear it when i listen to music only very silent click, nor when gaming. it is completely random Dell laptop , one click. could it be the fan from the dust? cani clean it without taking the back off?
Your theory could be correct that there might be dust in the fans that can cause the clicking sound. And there's no way you can clean it out without opening the back and getting in to the motherboard. Also check the HDD if it's a Solid state drive you won't have to check it. Open where the HDD is connected and observe it as well.
