BSOD only on cold start up, then restarts.

Ok, you have reason.
In these days I will buy a new key and I will post the report

I have formatted the pc and reinstalled Windows 7 and all my software and data

At the moment no bluescreen at the startup.
It is possible to know if the problem was related to avira and solved with the last update?

Ok, thank you for now.
Please, don't close the thread. If I will have new bsod, I will post here.

For now I prefer to wait one or two weeks
