I cleaned it out about .... hmmm .... never why?
First time posting here. You are certainly not kidding about this one. I have had this exact problem in the past with a fan going out. Didn't know what the problem was when the pc started shutting down and sometimes wouldn't even restart right away. After a month or so of this problem one day the computer started smoking in the back and I had to replace just about everything..2 hard drives..cd and dvd rom and a couple other pieces. With labor cost me over $400.
