Hi, I keep getting a black screen with cursor appear on my laptop after I leave it alone for a while (not being used). I have read many forums with similar problems but after login or at boot, for me it just happens randomly when im not using it. I have windows 10 and recently cloned my HDD to a SSD and replaced it (not sure if that had something to do with it). I've tried ctrl + alt + del, win + P and attempting to login (again) after reading some other forums but nothing seems to work. Does anyone have any ideas of how to fix this?

Thanks a lot for any help
