How to Build a Computer with
AMD Socket A Athlon or Duron Processor
Part 3 - Setup the Motherboard

Install the Heatsink-Fan.
32. Note the step on the bottom of the heat-sink fan. Position
the heatsink so it can step over the raised part of the socket.
Do not apply force directly on the CPU. That can break the die loose from
the rest of the processor. If you use a tool such as screwdriver to
assist, be careful not to apply too much force and do not to let it slip
off the spring and damage the motherboard. Keep the heat sink as close
to parallel along the sides of the socket where the heatsink does not attach
to the socket as can be managed. Push and orient the spring through
the heatsink and patiently work it to get the three lugs on the socket into
the three holes on the retaining springing. Try not to twist or wiggle
the heatsink while doing this.
Carefully lower the heatsink onto the CPU, making sure it is properly positioned
and does not ride up on the step on the socket. Hold the part of the
spring previously attached to the socket, to keep it in place, and the heatsink-fan
with one hand and attach the spring to the three lugs (out-down-in) without
putting excessive pressure on the CPU. Try not to wiggle the heat sink,
which, ideally, will come into contact with the die once as the spring is
35. Look along the sides and make sure it is positioned
properly and not riding up on the step. Yes, you can unlatch it and
adjust if need be.
36. Plug the fan wire into the appropriate jack on the
motherboard, neatly coil-up the excess CPU fan wire, and zip-tie it
to keep the wire out of the CPU fan, etc.
It is easier to do this now while the motherboard
is out of the case.
Install the Memory. Orient the motherboard so you are facing
the front of it. The memory module has two notches on the bottom:
one in the middle and another one near one of it's sides. Orient
the module so the notch on the side is to the left. Hold the memory
module with both hands and evenly and firmly insert it into the DIMM socket
labeled "DIMM3," the one closest to the CPU, and make sure
it is fully seated. The leavers at the ends of the socket will
come up when the module is inserted. Push inward on them to be sure
they are fully in place.
Memory modules can be plugged into any of the three
DIMM sockets in any order. DIMM3 allows more clearance for the
drive cables. Other motherboards may require that the memory be
plugged into a specific socket.
38. Push firmly down on the Award BIOS chip behind the
PCI slots of to be sure it is fully seated.
39. Verify that the Clear CMOS jumper header, located just
the left front corner of the VIA southbridge chip and left and aft of the
battery, has the jumper on pins 1 and 2, the two pins closest to the
front of the motherboard. Do not change this jumper when power is on. It
could damage the motherboard.
If you have a motherboard with jumpers, now is the
time to set and double-check them.
Your motherboard should look like this:
