SW2015 SP2.1 Crashes frequently

I've run SW Rx maintenance utility with no improvement.

The crashes I'm experiencing is like every 30mins!

I cannot use CCleaner because this will conflict with my work firewall and anti-virus program.

I'm using NVIDIA Quadro K2000 - a recommended graphics card by SW

I've also updated the drivers.

Currently the Global settings are set to Base profie

What can I do?
