Counterfeit installations such as yours contains heavily modified code that causes the installation to behave it unexpected ways. Analysing BSOD's and determining their causes on these sorts of installations is very unreliable.

My recommendation is to start with a clean slate, and install a genuine version of Windows. This will minimise the problems you are experiencing, and make subsequent diagnosis of BSOD's far more reliable. Once you are running a genuine Windows installation, and are still experiencing BSOD's, we will be happy to help you solve them :)
