Intermittent display corruption
I have an old Macbook pro:
2.4 GHz Intel core 2 duo
4GB Ram
NVIDIA GeForce 8600M GT
I've started getting intermittent display corruption issues, which you can see in this image:

These sometimes last for a few minutes and then go away. It is rarely present when I first switch on/resume the machine.
Any ideas about what this is? I'm guessing that it might be the dreaded death of the graphics chip?
I see that the extended recall of these parts is long over.
Any advice on what I can do?
Thanks
