Regular BSODS - During regular use and gaming

Hi, im new here and have abit of a dilemma. I'm not much of a computer wiz so please bear with me,

I've been recently getting BSODs following getting a new hard drive and a new case for my computer. The hard drive replacement and transferring of parts to the new case was done at a professional hardware store.
Its been happening every 2 days or so, and I've checked multiple threads, but can't seem to find any solutions to my problem.

Help would be greatly appreciated , my computer seems to be going through a phase of problems so if this gets fixed, hopefully it should put an end to it!
