So back to customer support.
Me: "My machine won't do anything."
Tech Support: "What's on the screen right now?"
Me: "It's frozen, it's showing my Windows desktop."
Tech Support: "Try hitting Ctrl-Alt-Delete, tell me what happens."
Me: (taptaptap) "Nothing."
Tech Support: "Did you hit all of them at once?"
Me: "Umm...just a second." (taptaptap) "I did that time. Nothing happened."
Tech Support: "Try it again."
Me: (taptaptap) "No, it's just sitting there."
Tech Support: "Move the mouse around. What happens?"
Me: "Nothing"
Tech Support: "Ok, last try, hit Ctrl-Alt-Delete again."
Me: "Still nothing."
Tech Support: "Hit your numlock key. Does the light flash?"
Me: "No."
Tech Support: "Ok, you're going to have to shut your computer off. Just press the power button, wait for a couple of seconds, and turn it on again."
Me: "I've heard that's bad for Windows."
Tech Support: "Um, well, you can't do anything else, right?"
Me: "No."
Tech Support: "Well, you can't hurt it any worse then."
Me: "But I've heard it's bad for Windows to just shut it off without shutting down first."
Tech Support: "Yes, but it's locked up. There's nothing else you can do."
Me: "Will it hurt my Windows?"
Tech Support: "Probably no worse than it already was by locking up."
Me: "Well...ok...but if it doesn't work, will you come over and fix it for me?"
