Thank you for taking the time to reply to me.

Yes, I have switched to DX9, as this is the only way I can play at the moment. As you say it is ‘ok’ to play in DX9, but not great - I can’t use the expanded inventory for example and it just doesn’t look as smooth, but at least I can play. Sometimes it freezes up a bit, but I don’t get the Fatal Error.

I hope it’s not the motherboard, but I’m really running out of ideas
