Please help! No idiotic answers, please!
know what you are doing before you start
make sure you and the frame of the computer have the same charge, when you handle a part or a motherboard first touch it by a large metal ground like a ps2 shield or the card slot cover. one static snap will surely kill many things
especially circumstances that's often bees. yet you are going to be waiting to tell that from a common electric powered hum. Plus it is going to be quieter at night. different noises can holiday throughout the wood. this could be a thermostatically controlled attic fan. as quickly because it starts getting warmer, it is going to kick on. The vibration can holiday throughout the framing and resonate interior the wall.
ALWAYS ground yourself first, make sure you have no static electricity on your hand( recommend wearing rubber gloves if possible, like those latex ones). Handle all parts with care. Make sure to unplug the power cords fully. Dont pull on any part too hard. Dont touch thee bottom side of the CPU. Dont touch the pins on the socket on the motherboard. Dont bend the pins on the socket on the motherboard. Always apply the correct amount thermal paste(A gain of rice size would do) to the CPU/heatsink when putting it on. NEVER turn on the computer without heatsink on the motherboard. ALWAYS put the riser between the motherboard and the case. Hmmm I think that's roughly about it?
