Windows 7 on KVM doesn't work anymore ...

Before I upgraded to Proxmox 3.1 I shot down all VM's. After the update to Proxmox 3.1 I startet all VM's again and all runs very fine without one exception: the vm contailing the windows 7 installation breaks while staring in blue screen (see attachment).

I replayed a backup - noting - means blue screen ...
I tryed to install a new installation - nothing - means blue screen ...

What's wrong or what can I do to fix that problem ?

Best regards
