Bios Mods -The Best BIOS Update and Modification Source

So I had my pc overclocked with ntune until I unlocked the bios. Everything appeared to go fine and I uninstalled ntune, deleted all the registry items, and the profiles in appdata. After multiple restarts, it was still running at 214MHz which is what ntune was set to run at. It wont let me reinstall, it says I still have the app. I tried driver cleaner and ccleaner. I had it running at 230 before and I would really like to get that back. Can somebody help plzzzz

Resetting the BIOS to its defaults is one possiblity...
Resetting windows to a former restore point is another option...
I had the same problem and it needed these two steps to solve it!

I appreciate the quick reply. I tried resseting the bios as you said but it didnt fix it. I dont have any restore points past yesterday and I dont really want to anyway because I downloaded and installed like 7 games and other stuff. Hmmm... Im gonna go try deleting anything nvidia.

What OS do you use?

vista ultimate 64
