Please check the processor temperature. Possibly its overheating may cause hanging of its components.

Also please check if the processor is powered fine. I mean the voltage levels is OK and there is no noise.

Also please make sure that you are running the latest BSP. Here may be some updates for GPU driver applied.

Have a great day,
Victor
