Ok…next round!

Had my pagefile locked and so it was to small to build a full memory dump. Now its done and if(!) this AvastTool will show up an UI (refuses to do so again - severeal reboots included) I will send those files directly to You…
Found out, that the crash happens when the system tries to go to energysave mode. Shutting down works as supposed to. There was another thread here with similar problems days ago wasn´t it?!

Sorry for all the inconvenience!

Greetings
Timo
