I am very new to Solidworks and have been using a template for my drawings for a couple months now. Today, however, it's very slow to load and freezes for very long periods of time before eventually the screen starts flickering. Once this happens, any keystroke or click of the mouse causes Solidworks to close. Any ideas on what's going on? I need to get this straightened out as soon as possible. I have attached my template and sheet format.

Thanks in advance
