Thanks. Although my soldering skills are quite good, I was just hoping I didn't put a cap in backwards. I marked down as well as I could, but when I got to the 5th, I noticed silkscreened on the board under where the capacitor was soldered down, there was a white colored-in spot on the diagram that indicated the negative post. I tried to check all of them, but it looks like it came out right.

The iMac is running great, except I have to reinstall. Not only did the powering up and shutting down cause issues, but there seems to be some back blocks on the hard drive by the bootsector.

Does anyone know if Zero out Data under OS X's Disk utility would mark off bad sectors, kinda similar to a full format on Windows would?

If it does, that should work. There are only a few, but I want to see if I can get this iMac back up. I would hate to have to spend more money buying a hard drive if I could just mark them off and either reallocate it, or just get rid of them altogether.
