Anti Static Precautions: Always Wear a wrist strap earthed to something metal (Case is usually convenient). This is especially important when handling the CPU & memory modules.
DISCLAIMER: This is a work-in-progress, not all solutions are "guaranteed", use info at your own risk. Not all topics are covered, only stuff that keeps reappearing in questions, or are thought to be important.
So you've maxed out your (or someone else's

) card and are looking at a pile of new shiny parts.
You're up for it & want to see everything running, but don't forget:-
The most neglected component in a PC Build is the builder/user, This unit should not become overstressed/confused during the build, especially if being used for the 1st time

.
Work slowly & methodically, plan what you do.
Familiarise yourself with the components so you are sure how they connect.
If unsure - DON'T DO IT.
If you have an issue, have a break, read up on the problem, if still uncertain
post in the forum. It's better to lose time than lose components.
Note: [O] = Optional but recommended steps.
Motherboard Preparation
Place the mobo on something non conductive, wood or cardboard from the packaging.
1) Clear Cmos [O]
Locate the
CMOS Jumper & clear
Cmos by moving the jumper to the middle & 3rd pin. The location of the
Cmos Jumper may vary (or may be just a button) It will certainly do no harm & now is the most convenient time. This helps ensure that components are registered correctly in
cmos when the mobo is powered up.
2) Mount the CPU.
THe CPU is particularly sensitive to static electricity so ensure precautions mentioned at the start are adhered to - wear the wrist strap.
2-1) Remove Plastic cover from socket - Slide to left.
2-2) Lift Cover from Right
2-3) Open Load Lever
2-4) Lift Load Lever & Lift/Open load plate
2-5) Holding CPU by the edges, align it to the Matching notches & alignment keys of the socket. Gently place CPU into socket.
2-6) Ensure that the cpu is sitting flush & level in socket.
If not, grip the edges and lift vertically out from the socket, & repeat 2-5)
2-7) When satisfied lower the load plate.
2-8) Lower Load Lever & secure behind retension hook.
3) Mount CPU Cooler.
There a wide variety of after market coolers available (see
Air Cooling
for recommendations), so you need to follow the specific installation guide for your model.
Some larger coolers require a backplate to be fitted underneath the motherboard. You should check the fit & ensure that it doesn't interfere with anything underneath the mobo.
You also need to ensure that heatsink fits on top of cpu & is not obstructed by heatpipes.
3-1) Apply Thermal Paste to CPU
Dual Core see Page 4
How to apply Arctic Silver 5 Intel Dual Core CPU
Quad Core see Page 7
How to apply Céramique Intel Quad Core CPU
As you can see, Dual core uses a vertical line of paste, whilst quad needs a horizontal line.
Cleaning/removing thermal paste -
Use
Isopropyl alcohol (IPA) - Can be obtained from chemist/drugstore cheaper than the cleaners offered by the thermal paste manufacturer's product. Imo just as effective but if you want it go for something like
Articlean
Use a small blob of IPA on a piece of kitchen towel or lint free cloth & gently wipe the surface to be cleaned.
Fitting Stock Cooler
3-2) Align heatsink so that Plastic legs are over the 4 mounting holes in the mobo. Push heatsink down so that clips pass through mobo holes.
3-3) Push down clips & using fingers or screwdriver, turn locking clip/leg 90 degrees to secure it. Seems best to tighten diagonally opposite clips.
3-4) Check from underneath mobo that all 4 ends are secured through mobo.

3-5) Plug in Fan Header from Heatsink fan, into fan header on motherboard. Note: The stock cooler uses a 4pin
PWM fan header. If your mobo doesn't have a 4pin header see this for more info
