Is my GPU dead even though I can boot from disk

Question

Is my GPU dead even though I can boot from disk

I canboot from CD, utilities says HDD is fine, I've got a Imac G5 1.8 PPC, but when I go to start from HD I get a black screen (although often after seeing the initial screen and circle).

Could it be that my GPU is up the spout? I have done a shed load of video on this baby, and it all happened when I moved it!

It has started up once but the screen was flickering and did look fragile!

If it is GPU - how do I tell for sure and can I fix myself?

Thanks

iMac, Mac OS X (10.3.x)
