I've had my hd 5670 for a few months now.All of sudden ,now when I turn on my computer the graphics card either doesn't display to the monitor, or it will turn on the monitor. But it will have artifacting.

Have you tried to replace the display cable? Similar had happened to mine until I realised it was my HDMI cable. If that doesn't fix, the most obvious and first thing you could do is re-seat the graphics card.
