UPDATE:
I got my hands on a older computer. I believe that was the problem. Check out the video
Thanks geh7552

Thanks for the help. I guess the first thing to try is a older computer. Don't have one handy. will post the results ASAP.

Hi, my name is James. Friends call me AJ. I would like to start off by saying thanks for any help you can give. Now, where should I begin... It all started about a year ago. I wanted to design & build small parts for RC hobbies and maybe other small projects. I really wanted to build my own CNC machine; but, I just absolutely didn't have the time or space. I decided to buy a small machine, learn the in's and out's of using it, and then add to it and build a bigger machine. I had no prior CNC experience when I ordered it, this was going to be a learning experience. The flashing lights, the smell of wood & metal burning, gizmos moving all at the push of a button, this was going to be great! With a big smile on my face, & the price being cheap,  I purchased a Chinese one off Ebay. Since this was a learning experience I really didn't want to put a lot of money into it. After a few weeks it had finally arrived (on a slow boat from China), it was packed very well! However, I was slightly disappointed with the instructions. It only came with one or two pages and it was very broken English; but, everything was self explanatory, so in no time I had it assembled. Now it was time for the computer end of this process. I didn't think the demo version of Mach3 would be enough; Therefore, I got the licensed version (500 lines seemed small), looking back it would've been enough for testing. Load Mach3 port pins, motor tuning, etc... very exciting, it's now the moment i've been waiting for! The motor is coming to life, the switch gets thrown, the box starts to hum, I use the jog button, at this point I'm feeling pretty damn good! All of the sudden the machine makes this god awful sound and the movements slightly stop or just completely stop. All this happened a little over a year ago, I have made many adjustments in port pins, checked the machine for binding/bent motor tuning. This is a last ditch effort, when I say "ditch" I mean if I don't get it up and going this time... I'm selling it and not looking back. I have no experience in electronics, I can solder. I have no programming experience either, so everything needs to be in simple, easily understandable terms. Below is going to be a list of my computer information/ software and my CNC machine, an just for laughs a few videos and pictures. And away we go!
**MY COMPUTER:
Dell Optiplex 740
**PROCESSOR:
AMD Athlom 64x2 Dual Core processor 3800+2.00 GHz (whatever that means)?
**INSTALLED MEMORY (RAM):
2.00 GB
**SYSTEM TYPE:
32-Bit operating system
**WINDOWS 7 PROFESSIONAL:
This computer is dedicated to this machine
Now for the CNC Machine
**BRAND:
YOOCNC
**MODEL:
6040z-JS3
This is the black box version with separate stepper drivers
**STEPPER MOTOR:
Two phase 57/3.0 A
**SPINDLE:
800-watt water cooled
  In the video below, it shows the CNC stall; but it made a full pass before stalling, that I edited out. I have made a few small parts with this machine, but something is still definitely wrong.
