itune crashes with webkit.dll in event viewer

I tried everything in the book, resinstall cleanly and removing all directories, reinstalling of the display drivers...etc anything that i can find in any forum but still itune is crashing and i just can't take it anymore with this software ... if i click on anything(store, library , menu ..etc) all will cause itune to crash.

Windows 7 64bit, nvidia display driver 64bit. (satelite toshiba pc)
