RAM RESEATING & FITTING PDF FILEWhat I do is unplug everything and then hold the power button in for ten seconds whilst touching the bare metal of the cabinet with my free hand. (This is advice from Crucial/Micron) Then I follow the .PDF file laying the cabinet on its side so that you are looking down onto the motherboard, so as to make life easy.
Don't wear nylon or other static producing clothing is the other bit of advice.
You can also make an Earth lead which is a 'normal' power lead but with the red and black wires disconnected inside the plug and cut back so that only the green earth wire is connected to the mains earth circuit.
You might be able to find a green plug so that this cable is readily identified.
Stay away from all capacitors!
Glad to hear that you finally got a good deal.
