a few weeks ago I was asked to take a look at a computer that wouldn't turn on. I checked if it was plugged you know started with the simple stuff. I checked if the voltage switch was on 115 and it was so I came to the conclusion that the issue was internal. I open up the computer and I immediately find the issue. This thing was dusty as hell I mean seriously it was like a country full of dust. It was all over the motherboard all over the heat sink all in the fan so I immediately started cleaning out what I could and after I was done I pushed the power button and it turned on. I only charged 10 bucks because all I did was clean it and it was working brand new. I wanted to toss it at the owner.
