Yes there may be issues related to the BIOS your motherboard has ,but Shogun 2 has a huge amount of stability problems no matter your hardware.
The game itself ,in spite of the huge amounts of patches , is simply broken.The game engine can t really do it s job properly ,it leaks or something.
Install latest motherboard BIOS to keep overall system stability ( it will crash only itself and not the whole computer) and use DX 9 while playing it ,it crashes less ,you can play a few hours before it drops
.
I would suggest you to play Napoleon instead ,it doesn t crash .
