I dont use system restore or the image. Never really cared for system restore. I have found it has never fixed most issues for me. I haven't used it in years but I also don't run into alot of problems. Most of mine are game or driver related issues. That don't require system restore, at least to me it doesn't.

maniac, so you are saying you install directly over your existing files? You don't delete the old driver n physX or the nvidia driver folder? You just let the nvidia installer do its thing basically?

 
Before doing ANYTHING with Nvidia drivers....
Open Precision (or Afterburner) and uncheck start with Windows and hit OK
Then shut down the program using the "X" in the top right corner and REBOOT
 
You are now ready to install
 
The answer to your question is Yes, the Nvidia installer package has its -own- uninstaller
to install a driver simply lauch the new driver installer in Custom Mode, all entires unchecked -except for Graphics driver and PhysX -and- put a check in "Perform a clean install"

whats the big deal with PX on start up? Why does it need to closed? is that a benefit for the software or we talking about a possible conflict if you we don't close PX?

Your saying you lost 40-50 frames? is that even possible? If it was wouldn't that be a broken driver basically?
I know its a beta driver but for anyone to lose that many frames is a bit concerning.

I got failed download also ! said i had to be online to download .
