Thanks for the reply, I did as the two links say with a slight problem;
When I went to delete the 'nvidia corporation' folder from my program files x86, wouldn't allow me to, saying it was being used by another process.
Alt control delete to processes, no nvidia programs were running. Task tray - nothing.
So after rebooting my computer after completing all the steps except deletion of the 'nvidia corporation' folder, my drivers had automatically reinstalled themselves, putting my screen resolution back to what it normally is.
I tried to uninstall the drivers again through control panel but since I deleted everything except the files that were 'in use' (therefore not allowing me to delete them) the nvidia programs couldn't be uninstalled ?
Anyways, I got rid of all my AMD and ATI stuff, gonna reinstall the nvidia drivers and give it a go.
EDIT: Game still freezes. Any other suggestions?
