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 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

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!

Good luck with your repair!!!   I sincerely hope that you've found this guide and disc helpful!
