Research Papers / Investigating how a computer and its components works [5]

hi, i am writing a research paper on computer hardware , and i dont know how to write my Thesis Statement , this is my introduction

Thesis Statement help on Computer Hardware

One day, when I was writing an article using my computer, suddenly the computer turned off. As I examined the desktop I thought that there is problem with the power. Later, I gave my desktop to Future shop to fix it, but they told me "we are sorry to tell you that you need to buy another one". However, I didn't give up and I tried to find out why my computer was broken. I wondered why this happened. I decided that I would investigate the questions, "what is PC, how does a PC works, and what is the difference between a Desktop and Laptop?" I believe that what happened to my computer are hardware problems, because I think that it doesn't matter what kind of software is downloaded to the PC, but rather what kind of hardware is installed, so I was curious to know more about Computer Hardware. The aim of this research is to investigate( the thesis statement)

i would be more than thankfull if somebody can help me with it

thanks
