I'm currently diving into C# and wanted to play around with the new Metro-styled-applications introduced with Windows 8, so I updated my Windows 7 to Windows 8 Consumer Preview.

The problem I'm facing right now is, that the system freezes after 3-5 minutes. It does not take any input from the keyboard or mouse and it does not recover (at least not in less then 10 minutes).

Since I have a background in Linux, I'd like to find some information about the cause of the freeze, but I have no idea where to search.

I checked the system-logs (under "System Control" -> "Management") but they only record that the system was shut down unexpectedly (doe to the face that I held down the power-button to reboot the PC). There is no useful crash-information in there.

I don't want to spend hours on randomly reinstalling drivers and doing things that "might help". Isn't there any place I can find some useful information about the freeze?

Before you ask:

• I installed Windows 8 as an updated on my old Windows 7 installation (which worked fine by the way).
• My hardware fits the minimum requirements (specs can be found here, the MacMini 3,1 model with 2GHz processor).
• I have updated the graphics-card drivers to the newest Windows 8 drivers from nVidia.
