I googled for solutions and most solutions I come across are people downloading the newer version of CPUZ. Mine is the most recent version so there's no issue in that.
What I'm worried is that the manufacturer might have questionable hardware to manufacture this laptop and it doesn't let 3rd party software to read the information. Is that possible?

The reason I installed and ran CPUZ is because my laptop is pretty slow for its spec. (Core i7, Geforce gt 750M, 4 gig ram) It has frequent lagging and loading times to do normal tasks like scrolling in Chrome and opening folders, accessing files, launching programs, etc.
