Radeon R9 270x crashing while playing Just Cause 3

Driver stops responding I recently started playing Just Cause 3 under medium setting so that my gpu does not have to take much of load. (My model is Radeon R9 270x Sapphire Dual-X edition). But unfortunately the game crashing in the middle and showing an error message. I have a AMD FX-4300 processor,8GB ram and 500GB ssd to support the gpu.
