I have the Radeon HD 5970 and this is what I can say:

- It's not an overheating problem
- It's not overclocked
- I have the latest drivers, even tried rolling back and it still happens
- Weird graphics like this happens to most games so its not just this particular one

This just randomly started happening with no explanation, I've had this card for 2 years, I just want to know if this means I need a new graphics card or if it's something else that needs to be replaced
