If I was a geek, I would've known when asked multiple times, "Are you sure you don't have another firewall installed on your machine?" to answer, "Yes, there are 2 besides the one I'm trying to install now" rather than saying, "No, of course not. I never installed a firewall on here."
And I would've known when asked, "How many network cards are in your computer?" to not answer that I only have the one I went out and purchased when, in fact, there is a built-in network card I could've been using all along PLUS the one that I went out and purchased.
And if I was a geek I would've known when told to "Boot in safe mode and check that you have Administrator privileges" not to answer with, "I most certainly should have Administrator privileges, I'm the only user! And what does it mean to boot in safe mode?"
