I am having some troubles with my ArcMap (v. 10.1), suddenly it started to crash. Firstly it crashed just opening my projects, then after few days it was able to open them yet crashed when I tried to select some .shp or raster or dwg. While now it is able to charge the project, select the .shp or raster or dwg yet if I try to use the editor tool (when I select a point, for instance, in order to use "move to"). Moreover, if I use another tool it takes some second (such freezing) before using it... Does anyone have some suggestions?
