MEMTEST
https://www.sevenforums.com/tutorials/105647-ram-test-memtest86.htmlthis one you willneed to make a bootable disk set the BIOS to optical (or USB if preferred) bootthe machine and let it run for at LEAST 8 passes unless the errors come upstraight away. Takes fair time to complete and some leave it running overnight. But it must be for at LEAST 8 passes unless as I say the errors come straight away.

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. For this reason, many analysts won't attempt it.

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 :)
