Since 2 months I have strange trubbles and crash with my display : sometimes de screen is splitted in 2 part : the rigth must be left and left must be rigth. (cf picture) I have also crash (my computer still on and don't restart, juste de display crash, sometime de sound too but usually only the display).
Sometimes after 2 minute the normal display come back but it's rare.
These crash happen usually during heavy task : Video Games and Flash player videos.
My question is : how to fix this ? Is it an hardware problem ? a software problem ? maybe my graphic card have overheating ? I don't know, Help me plz

Mother Board : gigabyte ga 990xa ud3
Cpu : AMD FX(tm)-8350 4.00Ghrz
Graphics : Radeon HD 6950 I'm running on Windows 8.1 64bit all driver updated.
