Oh, geez, fk2. I wouldn't know where to start with that. While I understand nvOC better than most, if I found myself in that situation, I would start over with a fresh image. I say that because the most time consuming part for me is in getting the OC settings right for each GPU and algo/miner. I presume you have those saved off in 1bash copies (I use a spreadsheet and 1bash copies) so it may be faster to just start over.

Just my 2 cents.
