A few questions: What is an early maintenance cycle? What are heat sink compounds? lastly, there is dust inside the tower, mostly covering the horizontal circuit board in there, but this is the longest Ive ever owned a computer, so Ive never blown it out. I just got it from storage recently, and only turned it on once before yesterday. I had a problem then too. All I want to do at this point is back up the important stuff in it, and after that I dont really care if it disintegrates at this point, because I just dont trust it to last much longer. I dont want to dump lots of money into it to replace a bunch of stuff just to keep it going another year or so.
