Sucked in

i have a problem with the computer. A few, actually. Recently I have encountered a few problems with my new computer. One: I think I have a built in microphone. I get feedback when I hit what looks like the microphone button on my computer....but when I try to record something it doesn't work, or I can just faintly hear my voice. Second: depending on the interface I am using some of my keyboard keys do not function normally. Typing in this post works fine, but typing in MS Word leaves me with all kinds of characters that I don't see on any of the keys. I have no idea how to turn this off. Third: I would really like to find a users guide for my new Toshiba Satellite so I can figure these things out, but I need to know what version I have and most people want to charge me $15 for what I think should have come with the computer at POP. Finally and most importantly my largest problem is how many hours I can log accomplishing nothing on the internet. I have spent the better part of 2.5 hours trying to answer any of the above questions. Really, what did my marathon of google searches get me......a few more questions, tunnel vision, a blurring headache and a feeling of resentment as i go to bed.
I am quickly learning that my blog may not be about what I can do, but about the myriad of things I do not know how to do. Suggestions welcome:) Goodnight!
