Yesterday, without a clear reason why, my photoshop opened up to a black screen. I've searched around and tried several of the fixes; changing my drawing settings to basic, restarting my computer, updating photoshop, and reinstalling photoshop. None of these have solved the problem. In the meantime, I can run the program as an administrator, but it still leaves me without the ability to create new documents.
Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue?
Have you Restored Preferences yet (after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved)?
