TechTalk: Damage Control
Take the cover off the PC and use your senses. The first
place to look, and smell, is the power supply. Usually, when the power
unit blows, you can smell the strong, acrid odor of fried metal. The
unit may be very hot if it just failed. Feel the hard drives. Are they warm,
or too hot to touch? Now, look carefully at the motherboard. The round
cylinders—technical term is capacitors—should look like the top of a
soup can. If the tops and sides are bulging, that’s a sign that the
motherboard is toast. A good technician can put your PC on
a hardware tester to determine if everything is working correctly.
