Motherboard repair and trouble shooting
Consider this: Do you have the tools and knowledge to do low
level component repair? Do you know what I mean by low level
If no is the answer to either of these questions then there is no repairing the motherboard
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 repaired/replaced.
Before opening your computer case check the safety precautions !!
If you have a proprietary computer there in not a lot you can do besides diagnose your
problem then call the manufacture support and get it replaced.
Trouble shooting motherboard problems.
Most manufactures buy their bios from programming houses like Phoenix. Some
manufactures have their own in house bios programs, like Compaq (now HP). These 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” codes (Power On System Test). Some also have „beep” codes, the computer
speaker beeps a certain code for different failures. The main thing is when you turn on
the computer you either get a number on the screen, the computer starts beeping, or it
dumps into the BIOS setup screen.
I can not list all post and beep codes here but they can be found by noting the BIOS
program name when the computer starts up, then searching the web for the codes by the
programming house name.
From the post or beep code you get a general idea of what the problem is. Memory?
Video? Keyboard? Mouse? and so on.
Most problems with components can be resolved fairly easily and quickly. Sometimes
reseating the component will take care of the problem. Sometimes removing the
component and putting it back in will clear the problem. If the problems persist after
reseating it then it is dead, needs to be replaced.
CD Rom or DVD Rom Drive repair

Dead CD ROM or DVD ROM drive, repair or replace?
As I mentioned in the introduction, repair of components is not economically viable. A
really observant and talented individual could repair a failed cd rom, if it was a
mechanical failure. Or if you had two of the same model drives, one that failed
electronically and one that failed mechanically, you could change out the bad circuit
board on the mechanical failed drive for the good circuit board and save your self thirty
dollars. Or you could go buy a brand new one and replace it.
Check the case page for opening case and precautions. Remember Safety First!
Before you loosen up the drive you should disconnect the power cable, the drive
cable, and the Audio cable. If you can not get your hand into the space to disconnect the
cables pull the drive carefully out until you can gripe the cables. Usually the IDE Drive
Cable will pull loose with a little force, there is a latch on the Audio cable. The cable that
will give you problems is the power cable, they are made to not vibrate loose. You can
use a pair of pliers to wiggle it loose, do not squeeze it to hard, it is plastic and will break,
with a firm grip on the plug, working it back and forth while pulling gently will get it
Note the wide cable, it is the IDE Connection cable, it will have a red stripe down one
side. This indicates the # 1 pin side of the cable connector. Some cables that have been in
the computer for a long time tend to harden from time and heat, you should not have to
change the routing of the cable. Some cable connectors have a guide pin that will match
the connector on the drive, this keeps you from connecting the cable backwards, some
don’t that is why you have to note the stripe. Look at both drives, the IDE cable connector
should be orientated the same, note the notch for the cable in the connector on the drive,
are they both orientated the same or are they opposite? If they are opposite then you will
have to reorient the IDE cable before you install the drive.
Look at the back of the drive, next to the cable connectors there should be a double row
of small brass pins. These pins are called jumper pins. You will see one or two small
plastic covers (called Jumpers) over some of the pins. On the drive there should be a
diagram that will tell you what the covered pins do, this is the drive selection.
Your choices for the drive selection are:
Set the old drive aside, check the new drive, you need to match the drive select pin
setting on the new drive to what the old drive has. Either Master (two drives on same
cable and this is the primary drive), Slave (two drives on the same cable and this is the
secondary drive), or Cable Select (best selection for a single drive on a cable).
Once you have the drive selection set, reverse the removal sequence to install the drive.
Once you have the cables reconnected and the drive back in it’s bay put the cover back on
the computer. I do not recommend powering up the computer with the cover off.
Check the drive:
When you power up the drive the startup sequence checks all drives, you should see
the cd drive activity light come on, push the drive eject button, the tray should open if
not, power the system down, you have a problem. (go to trouble shooting)
If you have power to the drive let the computer power up, put a cd in the drive, see if you
can access the drive
Windows XP can look sexy but displaying all the visual items can
waste system resources. To optimize:
1. Click the Start button
2. Select Control Panel
3. Double-click the System icon
4. Click the Advanced tab

1)te duci la control panel
4) bifezi „use mouse keys”
5) bifezi”use shortcut” si/sau pui „use mousekeys when num lock is off”
6)bifezi „hold ctrl to speed up and shift to slow down
6)iti selectezi viteza din barele alea. Eu le-as lasa pe la 75% pe amandoua
Acum inchizi num lock si/sau apesi ALT din stanga + SHIFT din stanga +
NUM LOCK ca sa pornesti mouse keys. sus/jos din num8/num2; stanga

mouse-ului iar CTRL mareste viteza.
Inainte de a face orice fel de optimizare ori de a va juca cu sistemul de operare, ar trebui intotdeauna sa faceti un backup! De vreme ce Windows XP are are o functie foarte interesanta – System Restore .
Mergeti in Start -> Control Panel -> Administrative Tools -> Services. Aici va va aparea utilitarul Services care arata ca in figura de mai jos. Nu va uitati dupa Automatic Updates – era deja scos impreuna cu altele.
De aici puteti activa sau dezactiva serviciile ce ruleaza pe calculatorul dumneavostra. Multe dintre ele sunt nefolositoare, dar unele sunt absolut necesare pentru ca sistemul sa porneasca. Dezactivand unele dintre ele putem obtine un castig de performanta, mai multe resurse disponibile, opriri ale calculatorului mai rapide si timpi de pornire mai mici.
Dati un click dreapta pe serviciul numit Automatic Updates
In ecranul urmator uitati-va unde scrie Service Status. Daca aici scrie Started atunci dati click pe butonul Stop. Acum, unde scrie Startup Type modificati in Disable si apoi dati OK. In acest moment ati reusit cu succes sa dezactivati Automatic Updates si sa impiedicati ca acesta sa porneasca de fiecare data cand porniti Windows smile.gif In sectiunea urmatoare veti gasi lista completa a serviciilor, impreuna cu descrierea fiecaruia, si cu recomandarea daca sa-l activati sau nu.

Here’s a DOS trick for Windows 9x, that will reset (delete) your motherboard’s BIOS password (aka CMOS password) without any need to open up your computer to remove the battery or mess with jumpers.
This method can come in very handy in the event you ever lose and forget your BIOS password or if you acquire used computers where the unknown previous owners had BIOS passwords set (in fact, this happened to me long ago—I was given a used computer, but there was no way I could enter the CMOS to make changes). It’s important to note here that the password we are talking about is only the one that prevents a user from entering the BIOS setup at bootup, not the one that stops you from getting past the boot.
