hang up

Not enough info provided to give any info to a particular solution to the hangup problem
There is a couple of instances where the system will collect information in preparing the Windows directory
Ther is not a way to trouble shoot a hangup duringinstall

It sounds as if a piece of hardware is causing the system to hang during the detection phase of installation. You could remove all hardware except for the video card, memory, hard disk and cd-rom drive, then try installing. If the install goes through, add your other hardware back in one at a time. I have seen USB devices in particular cause this to happen.

Hope this helps...

More information would be nice, but you can go to http://support.microsoft.com/default.aspx?scid=kb;en-us;Q129260 and find some information on hang ups during installation. If you have an anti-virus be sure to disable it before starting. Also if you are using a product like Go Back, disable it before installing.

Good luck.
