Dell Mobile Precision M6800 crashes

[onzki]

Hi everyone! my Boss' PC have this specs-
CPU: i7-4810MQ
Video: AMD Firepro M6100 2GB
OS: Windows 7 64-bit
and it crashes every time he moves from one scene to another even though the scene transition disabled already. Model is a big mixed-use complex, about 280 MB.
Could it be the graphics card? Anyone having similar issues with AMD Firepro?

Thanks!
