Crashing ArcGIS 10.3

[PhyllisTogarepi1]

I installed the current ArcGIS software a little over a week ago and I was happy with its efficiency until yesterday when it started slowing down and finally crushing whenever I try to execute a command using the ArcToolBox. I am frustrated as I have tried to repair the installation but ArcGIS keeps crushing. Someone please help me with a solution.

Also try running the geoprocessing tool in foreground (Disable Background Processing). Geoprocessing > Geoprocessing Options
