The other day I was cleaning all the dust from my computer. I went to turn it on and everything was working fine for about 30 seconds. When it got the Windows loader screen, it just suddenly shut off. So I turned it on again and the same thing happened. When I did it a third time I saw an error on the screen about the CPU being too hot and it shut off again. I talked to a couple people and one said that it was a bad processor heatsink/fan and the other said it was a bad power supply. Before I go and potentially waste money on something I may not need, I would like to get a definitive answer.
-Thanks.
