Here's some advice about electrostatic discharge: Electrostatic discharge is simply the discharge of built up static electricity. Electrostatic discharge however, should not be taken lightly when working with computers.
Only 10 volts of electrostatic discharge can damage computer components. Walking across a carpet can generate up to 12,000 volts of ESD (electro static discharge). Electrostatic discharge is especially a problem in dry and cold climates.
Electro Static Discharge can cause two types of damage in an electronic component: catastrophic failure and or upset failure. Catastrophic failure destroys a component beyond use. An upset failure damages the component so that is does not perform well even though it may function to some degree.
At the very least, you should touch the bare, unpainted metal of your computer case frame before handling any computer components to prevent damage to any parts in your computer.
Avoid touching chips or traces on any computer chips as you handle them. There is danger of electrostatic discharge damage.
