Well i have a HP Desktop that makes my head hurt because it is so slow. It used to be fast but now its rediculous. So i decide to start everything over like it new. I want to reformat everything but i can not seem to find the CD that came with the darn computer. Is there a free way or any way that i can do this without the CD? Free if possible. What are the benifits of reformatting if you think you have a virus? What are the proper backup steps?
