Many people who have updated to the latest Forceware version 169.21 have had problems including me. It's not very popular. However, I have been using Forceware version 163.75 and it's been working great. I noticed that since I upgraded from 93.71, things look a bit nicer on the screen. Also, if you download and install Ntune, you'll be able to access the more advanced features (if you card supports them) and overclocking features. If you want to use any Forceware version before 97.31, you can use Coolbits to gain those features (Coolbits will change and add a few lines in your registry and it's totally safe).
