So i just put a new gtx 560 ti into my computer and everything seemed fine but when i installed the latest version of the nvidia control panel, i clicked on the various menus fine but as soon as i clicked the 3d management settings the thing just crashed... now everytime i go into the nvidia control panel it crashes and i am unable to change any settings.. can anyone help me please!? I have played games ok so i don't think there's anything wrong with the card?
