I run a computer business where we build and repair PCs. I want to
find out how people in this business like Geek Sqaud do repair?? For
example what kind of hardware  and software techniques and kits they
use for PC diagnostics...
Also I want to buy a PC diagnostics kit for my busniess. I need
recommendations for which one I should buy.....

Thanks

Really the best troubleshooting tool ive found, is my own knowledge +
the internet, once you truly understand computing, all troubleshooting
stems from a basic tree of options.

Thats true but I wanted to speed up this process of diagnostics and
also if I have employees and they are not top notch experts, these
tools can be very helpful. I hope.

Thanks

I wouldn't call Geek Squad top notch by any means.  Honestly, all you
really need, as far as physical tools, are a screwdriver and maybe a
can of compressed air.  Software really comes down to personal choice.

I have experiences with pc diags, I use work for a computer reseller
and found that PC Doctor is pretty good diagnostic software for
troubleshooting. There is a DOS and Windows Version both with
automation capability, which we leverage quite extensively.
I currently work with IBM servers, which uses PC ? Doctor to test
there server for troubleshooting and service diagnosis.

I also build & repair computers. The best diagnostic software, in my
experience, is available as freeware. Here are my recommendations:

"Ultimate Boot CD" at http://www.ultimatebootcd.com/
Download, burn image to a cd, and it will do just about anything.

"PC Wizard" at http://www.cpuid.org/index.php
Excellent program to collect hardware data on an operating PC.

"Belarc Advisor" at http://www.belarc.com/free_download.html
Gives listing of software, and some hardware on an operating PC.

"BIOS Wizard" at http://www.unicore.com/bioswiz/index2.html

"Magical Jelly Bean Keyfinder" at
http://www.majorgeeks.com/Magical_Jelly_Bean_Keyfinder_d2612.html
Shows product key for many Microsoft operating systems & applications
installed on a PC.

"KillDisk (Free Version)" at http://www.killdisk.com/
Destroys contents of a hard drive & returns it to "factory fresh"
condition (removes all data & partitions) - VERY useful.

"FDISK (Windows ME Version) at http://radified.com/Files/
Partion a hard drive. Windows ME version supports large drives.

"XS SysDetect" at http://www.majorgeeks.com/XS_SysDetect_d358.html
Provides memory & primary hard drive usage on an operating PC.

The best thing to do is to put the suspected component on another
computer , so you will see if it work or not ; there are some programs
for hardrive diagnostics (from the producer for ex : maxtor , seagate
,etc) ;
The newest motherboards have an acoustic sistem that tryies to locate
the problem , or other boards like those that have n-force 4 can
locate the zone with trouble ; In case there are other components
there are simmilar tools : for monitor the Nokia testing tool , for
sound cards (you'll se if you can hear it , ) for video cards you can
test the card's capability by specifications .
So there are some tools , but nothing like in the movies :)
