RE: STOP: 0x000007B xp setup
Looks like some kind of hardware fault. It is necessary that you must simply disconnect all the connected hardware and then test back. There can be printer or any pci card connected to your pc. Or even the lan cable. Just disconnect everything and then run the setup back. I am sure that will be more than enough to fix the problem you are facing. Then run the setup back from scratch and test again.

Try to change the disc. I am talking about the installation cd. Just replace the same and then check back. I think that will be enough helpful for you. Just arrange a different installation media and then test back. That will be quiet enough to fix the issue you are facing. Sometime the problem lies with the cd which does not has proper drivers to access your hard drive.
