Diagnostic Guide - Use this disc at your own risk.
Finally there is a
proven method for diagnosing computer problems!
Every computer is
different, and every problem is different, but with this guide, the DVD, and
some patience, you can succeed at repairing your computer.
With this DVD you can
successfully diagnose a computer that won't boot up properly, remove viruses,
test the components of the computer to figure out what needs to be replaced,
and get back on track in-no-time.
You can even use the DVD
to replace an operating system thats been corrupted.
ie: Windows needs to be re-installed, but you
have no windows disc [just click the
'install release' link on desktop]
If you get lost or need
more help, remember you can search for more help about the particular problem
on google.com and hear what other technicians have to say.
First things first:
always check connections first, and check to make sure fans are operating
properly when you first turn the machine on.
The fan should blow cool air, or warm air, NOT HOT air. Everything
should be connected properly. Memory
should be seated well into it's slot, heatsinks should be tightly pressed onto
the cpu,
and all jumper settings
on drives need to be set properly.
Bios settings should be
checked [or restored to factory default] and time and date should be set.
When you turn on the
computer
Your computer should
POST - power on self test
It will display some
information or a splash screen and show F1 or F2 for setup, F10 or F12 for boot
menu. [sometimes its other keys like esc or delete]
you need to tap these
keys quickly when the computer first turns on to access the menu or settings.
Setup will bring you
into the computers bios setup - these settings control the functions of the
motherboard and the computer.
Boot menu will allow you
to choose your startup device - DVD, hard drive, etc.
Sometimes a computer
won't POST
when a computer doesn't
post it will beep, make a series of beeps, display a black screen, show lines
across the screen, etc.
this is most likely
caused by a memory issue, or video issue, or even a bad motherboard.
If this happens reseat
the memory, or replace it, check your cpu, and try again.
When testing again with
known-good memory and cpu = if symptoms persist -you probably have a bad
motherboard. Check the motherboard for
bad capacitors - they look look like little batteries that have swollen up,
sometimes can be discolored or even leak fluid.
Bad capacitors are a sure sign of a bad motherboard.
IF computer POSTS but
doesn't boot up 'windows' or other operating system.
says 'no operating
system'
Gives a 'file missing
error'
or hangs during
startup
this is a sign you may
have a bad hard drive, or damaged files [system needs re-installation]
IF your computer boots
up windows, but its slow/doesn't work right/ it may have viruses, or damaged
system files.
Continue to test all the
hardware as described below, backup the data, and then run the antivirus
utility to scan the entire drive to remove any infections - reboot.
If system is still slow
or doesn't work properly- you need to backup data and replace the operating
system to repair the issue.
Starting up the
Diagnostic DVD
Enter your boot menu or
bios settings and set the computer to boot from DVD [optical] drive.
[push F1, F2, F10, F12,
esc, or del - as soon as the computer turns on to access setup or boot menu]
Insert the disc, and
select DVD drive from the boot menu,
[or choose to boot DVD
first in setup, and reboot.]
If the disc does not
boot, replace the DVD drive, and continue.
If you don't have a
replacement DVD drive, You can use another computer with a working DVD drive to
create a bootable iso of this DVD - just use the 'startup disc creator' utility
in the system menu to create a boot-USB from this disc.
Make sure to select
'discarded on shutdown' for saving files-
before you create the usb drive or it will not boot up.
After Booting up the DVD
A menu will appear
Choose memtest.
Test the memory for 20
minutes or so, and if there are no errors, reboot.
IF there are errors,
reseat or replace memory and test again until it passes.
After rebooting
This time at the menu
choose the top choice [boot live DVD] or just wait for it to start.
When the desktop appears
READ the README FILE
1st.
Open the testing folder
and double click the 6 minute stress test.
If the system stops
working, freezes, or shuts off during this test:
It's likely that you
have a CPU heat problem, motherboard issue, or bad cpu.
Fix the issue, and
proceed. Do not continue to test the
computer before fixing this issue.
IF you can't resolve the
cpu/motherboard issue, you can connect the hard drive to another computer to
backup the data/test the hard drive.
After the 6 min stress
test runs without a problem
Open Gsmartcontrol.
Double click the system
hard drive
click the perform tests
tab
run the 'short test'
If it fails you know
that the hard drive is definitely BAD.
IF it passes, you MAY
still have a BAD drive, you'll need to run the extended test to find out if
it's ok or not. [takes a couple hours]
If it passes the
extended test you can continue to use the drive, but you may need to reinstall
the operating system or remove viruses.
IF the drive is bad -
insert a thumb drive or blank dvd and backup any important personal information
using the program K3b [burn DVDs], or drag and drop files onto your thumb
drive, with the file manager.
If you can't access the
files to backup the data
Try testdisc,
magicrescue, or recoverjpeg utilities included on this disc [view the readme
for extended info on these utilities]
If the disc isn't
detected in gsmartcontrol, or isn't detected in file manager it's possible that
the drive is completely seized, or completely damaged, or you could have a
jumper setting issue or a bad hard drive cable.
If the drive is seized
or completely damaged, and there's important data on the disc you could contact
a hard drive expert to repair the disc and extract the data - [usually very
costly]
Once data is backed up
Run the 60 minute stress
test to be completely sure that there are no heat issues or motherboard issues.
After you've got your
data backed up and you've passed a 60 min stress test.
Shut down the computer,
and install a new hard drive [if need be] and re-install your operating system
of choice.
[or reboot this DVD and
double click 'install release' from the desktop to install xubuntu]
If you didn't need to
install a hard drive and you've determined that you need to run the virus scan
to remove infections, do it now, and reboot the regular operating system to
test it. [shutdown, remove dvd and
reboot]
If after removing
viruses your system is still not working properly - re-install windows if you
have a disc Or install xubuntu from this DVD.
['install release' link
on desktop]
Once you've installed
Xubuntu to your hard drive you can customize the system any way you'd like,
store your personal data, and even create backups easily with 'remastersys'
included in system menu. Re-master your
own version of this system any way you'd like!
If you need more
applications just install them easily from the ubuntu software center, and
enjoy!
Once you've got your
operating system and software re-installed, restore your backup data.
And you've got a working
computer again, and your data is safe, and you've verified that your computer
hardware is healthy.
If you're waiting for a
replacement hard drive to arrive in the mail, you can boot this DVD anytime,
without installing anything, and have basic functions of your computer to
browse the web, burn discs, play media, access email, and more!

repair!!! I sincerely hope that you've
