Panic errors

[lukestratton]

Hi

We have a Mac Pro 3,1 - Xeon 2.8GHz with 6GB RAM. We are constantly receiving Panic errors 'Please restart your computer'.

I have attached the error log to this post.

Can anyone shed some light on what might be wrong?

Thanks

Luke

It seems, it has to do with your Nvidia GPU:

Do you have another GPU you can try?

Graphics card or graphics card drivers for sure...A spotted, see if you can try a different card in there. If it works, chances are your existing card is shot.

Thanks for your help. Certainly looks like the graphics card now you've pointed it out. Seems a bit strange as we've just replaced the graphics card albeit an eBay replacement.

Does anyone know where to download new drivers, or are they only available through software update?

Thanks
