Content Fields Out Of Alignment

I am faced with an odd-ball issue and I was hoping someone could give me some insight. Within the last three days I noticed that cck content fields (both Node module form and custom) have become completely out of whack in regards to rendering. Inline fields automatically kick out several spaces to the left or go out of alignment. Body fields lurch over far to the left. Links area elements in certain cases will also join body elements to the left, sometimes not (see attached pictures).

To resolve, I have:
- Tried different browsers (no effect)
- Changed themes (Garland, Zen, Newsflash all show the same problems)
- Restored to older SQL backups (no change)
- Rolled back all recent module upgrades (no change)
- Deactivated any module that I can without breaking base functionality (no change)
- Firebugged the site to see if something is messing with the css (nothing)

It seems to revolve around cck fields, so that if I move the body field to the top in Content Management > -type- > Manage Fields, for example, the body will align correctly, but the custom elements and links area gets knocked out of alignment. If anyone has a clue as to why this is happening or can push me in the right direction, I would be most grateful.
