Well, I just bought a hand compressed air thingb (so I do not have to constantly buy compressed air) and I turned off the tv computer, took the lid off, and squeezed .... my goodness, a cloud of dust erupted. I do not think it had been blown ever. Then I put it into the fan to blow the CPU.... everytime I squeezed more and more dust came out. Now I fear that because I was nice to it the computer will rebel and break.
