problems with shutting down while installing

[Jtkiefer]

While trying to install the AMD64 version the system I am running (specs 
listed below) keeps shutting down.  I have tried changing out power 
supplies which has not helped and I have had no problem running LiveCDs 
on the system so I don't think that's the issue.  Any help on this would 
be appreciated. Thanks.
