Issue working in 3D

I have been working in a 3d drawing fixing some triangles for a rendering, using Microstation SS3. When I am in the process of drawing the new triangles in my screens go black and then it comes back and the image below displayed in the lower right corner. Has any one else seen this issue. Is this a software issue or do I need to contact NVIDIA or Dell on this issue. I have also has it where the whole computer freezes and I have to reboot by pushing the button, and had it crash and give me the blue screen today.
