I have had this problem ever since my dad built this computer and even he has no idea what has happened. I am not a computer genius but I came across the windows helps forum so now I am deciding to give it a try. This blue screen occurs most when I am playing games or when I am trying to rate my computer's assesment through the windows experience index sometimes it would say windows assesment tool has stopped responding in the middle of the test, but I think I have finally solved it through the clean boot method that windows has shown me. But the BSOD still happens and I do not know why. May anyone help please, here are my files.
