Quote: "I can't find any of the specs and I don't know them off the top of my head. Would cleaning up my computer work like deleting all of the things off the hard drive that I never use?"
This is a common misconception. Often, the amount of hard disk usage will have minimal impacts on system performance, because they work so fast nowadays. Disk clean-ups were prioritised to improve performance in the, let's say, 1960's.
I suggest you download a mod or the latest version of FPSC. You can obtain your specs by creating a new shortcut to 'dxdiag'. Just type it in.
My karma ran over your dogma.
