Solidworks 2017 SP1.0 has become very unresponsive

After several months of use Solidworks 2017 has become very slow and unresponsive in the last week. This is after no changes or updates to system that I know of. Running on Intel i5-6600 Core and NVIDEA Quadro K420 graphics card. Reinstalled software and noticed no changes. CPU utilization is minimal at less than 5 percent, memory usage is around 35 percent.
