Checking if two cells have a different value?

Hello, I'm trying to code a little program to check if my matrix is symmetric. I have a 96x96 table (with headers on row A and column one that should be counted out) that should be symmetric (e.g. B4 = D1, C4 = D3 etc...).

I accidentally modified some cells, thus it's not symmetric anymore.

I would like to identify cells that are not identical (symmetrically speaking), using VBA. I had a few ideas using While loops but couldn't get through with it :-/ Any help?

It's supposed to be a symmetrical matrix containing only ones and zeros with ones on the diagonal.
