My dad has a computer that's about 3 years old that he's had for a year or 2. He told he never cleaned it and I flipped out and went to work. I took everything out and cleaned it as I do with my own system. After I put it back together it won't catch the VGA connection. I tried 2 monitors and 3 different VGA cables. Also I put his HDD in my computer and when it gets to "Starting Windows" it just resets. What can I do? Is it fried or is there a fix?
