Hi,
That looks like a Graphics card going bad to me, were you overclocking your card?
I would take it apart and apply some new thermal paste, a good quality one..
In the past when I've had cards start doing that, they generally don't last very long..
They are usually ok in Safe Mode as they are not being pushed..
