The Blue-Screen-of-Death (Dust Bunnies in the CPU!) Part 6
Use the canned air to blow out the dust bunnies that are visible (if you see a thick layer of dust, relocate outdoors so you don’t get people sneezing uncontrollably as you spray on) paying close attention to the CPU itself and the heat sink. A vacuum cleaner would also be good but use it with caution for it is mostly made of plastic and it can damage the computer. It can also be too powerful that it sucks some jumpers and other small parts into oblivion. Check for corroded pins on the connectors and use the contact cleaner (others use an eraser which not only removes the gold plating on the contacts but abrades them to the point they thin out).
