Hardware error?

[FMF]

Hi all,
Whenever I try and play world of tanks after about 30 minutes my computer freeze's and only a hard reset will work.

Is this a graphics card issue or is there a way of diagnosing this?

My very old specs are
Q6600
ATI 4870 512mb
4gb DDR2

Thanks

Looks very much like a dying GPU to me, goosed VRAM specifically.
