Just bought a new system and my card games tend to crash the Hex game and stall it out.

My Game name is Thunder.
AMD FX 9590 Eight Core Processor 4.70 GHZ
16.0 GB
64 bit Operating System. Windows 8.1

Computer knowledge wise I am just dangerous enough to think I know what I am doing to screw things up so if you need further information I am going to need some detail on how to get it. Plus the system is new so not sure where to find stuff.

Hope you can help thanks.
