I have a Palit GeForce GTX 980 installed in my desktop. I t has behaved perfectly since I installed it (3 years ?) Over the last month I have been having prblems with it at startup. I run 2 monitors from it. One on mini diplay port and the other on HDMI. For the past few weeks when I switch on the main monitor displays correctly but the second one alternates between the desktop picture and a black screen. I have tried it with 2 different monitors with the same result. I have swapped the leads around and tried different leads and get the same problem. The drivers have been updated to the latest and I have also tried previous driver. Still get the same problem. After between 15 -30 minutes it "usually" sorts itself out and stays OK until I turn it off and back on. Anyone any ideas please?
