A short tutorial
on how to repair motherboard.
Consider this: Do you have the tools and
knowledge to do low level component
repair? Do you know what I mean by low
level component repair?
If no is the answer to either of these questions then there is no repairing the
motherboard (mb) for you. There is however things that can be done to a main board
that is malfunctioning that does not require repair of the board itself. So this
section will deal with trouble shooting and things that can be
Before opening your computer case check the
safety precautions !!
If you have a proprietary computer there in not a lot you can do besides

Most manufactures buy their BIOS from programming houses like Phoenix or
manufactures have their own in house bios programs like IBM, or Compaq (now HP).
bios programs have a section for diagnostics, some of them are accessible by the
user, others are not. Most have a way to tell you there is a problem with the
computer, these are "post" (Power On System

I can not list all post and beep codes here but they can be found by noting the

Most problems with components can be resolved fairly easily and quickly.

The main thing is troubleshoot the problem before replacing it, this will

are associated with the power supply (see top image, the two rows of caps at the
top and on the right hand side of the CPU are NOT power supply caps!). You can
