Message in Protools 11 and wrong display

I have a protools 11.3 with digirack 003 on a PC windows 8.1 system.

When I record after few minutes a message appeared on the screen :

violation access, impossible to read memory 0x00000033DF84A.

The waves (in Protools track) on screen diseappare but protools continue to make good recording.

I have an AMD Catalyst R9255X graphic card.

The computer is a Fujitsu Siemens PC with icore 5 processor and 12MB memory.

Do you think that the problem come from my graphic card ?

Thanks a lot and apologize for my poor english.
