@ Jean Horten - Yes, it is a laptop, and it is my understanding the card 'can' be replaced (not soldered like many). I did try SL viewer with same result. Certainly couldn't hurt to try another. And in answer yes I have cleared my cache, but thank you so much for taking the time to respond.
@ Drake - Hadn't thought on the FS group. Good idea, and thank you for being so kind and responding.
