But nVidia updates really provide performance for PC. Thatsfore I update it regularly. Regardless big products like thoose shouldn't crash each other.
By the way after all this I couldn't uninstall Fences completely. I sent a message authorities and they gave me a .bat file for this. And I wanna share with people having the same problem like me.
Here is the link (open with Internet Explorer): http://sd.stardock.com/zubaz/apps/Purge_Fences.bat
This file for Windows 7 64 bit operation. Save your desktop, right click it and select "Run as Administrator". Reboot the computer and reinstall the application.
I haven't try yet. Because I formatted my PC and don't need this for now.
