Hi, thanks for your reply.
Yes, I am absolutely sure I am plugged into the GTX...
My 2 monitors are plugged into the GTX DVI ports.
If not, I would not able bale to run any of my high end graphic and editing applications.
Also, in the Device Manager the Graphic Processor shows GTX 980.
On some boards I have seen similar issues discussed where Pete Dawson was able to limit some of the crashes with changes to FSUIP.
However, his changes has not helped my issue.
Thanks
