OS X Mountain Lion Crashes When Installs Xcode

So I just recently upgraded to Mountain Lion and so I needed to upgrade Xcode to the newest version. Well everything was going fine during the download but then about 1 minute after it started installing my computer just instantly crashed and rebooted. When I got back into OS X, I was greeted with this error:

Your computer was restarted because of a problem

If I try to reinstall (including re-download) it does the same thing. Does anyone know about this problem or how to fix it? I've searched Google and have not come across anything like this.

Thanks

If anyone ever see's this I figured out what it was. It was the VirtualBox kexts in /Library/Extensions/. Once I removed those the installation went smoothly.
