Ok, so this is a little strange. I got very close to my clip and I could see it was hitting a transistor on the board that is very close to the nor chip. Apparently other people with some slim consoles have had similar problems. So I shaved down some of the plastic on the clip and I think I got it to sit a little better.
But now my ps3 is doing what it was during the very first post of this particular thread. It turns off no matter what combination I use of the first two switches, and if I try to press start before it turns off, I get the 11000010 error, just like in the first post.
