Question Infrequent Black Screens

[JFS2705]

Hi,
Recently I have been experiencing infrequent black screens on my PC. It only happens on my primary display and not my second monitor. I believe it is an issue with my GPU but I don't know how to fix it. Any help world be appreciated.
I have a Strix GTX 1060
Thanks
