Welcome to our forum alle.

It appears according to your logs, you are running a counterfeit installation of Windows 7 Ultimate.

From you log.

System Boot Time: 4/12/2017, 4:55:37 ££
System Manufacturer: Gigabyte Technology Co., Ltd.
System Model: To be filled by O.E.M.
System Type: x64-based PC

Your code is for this.

Win 7,Ultimate,ACER/GATEWAY/PACKARD,XXXXX-OEM-8992662-00006

Which means you are using the code for a Acer/gaqteway/packard on Gigabyte motherboard.
You must start off with a correct copy of Windows 7 along with the proper matching COA key to make your operating system legal.

Our BSOD team will gladly help you once a legal Windows 7 is installed and activated.
