Opening images in PS only shows a sliver of image

[Sascha5FD0]

Hi all,

   Yesterday, suddenly when I open new images in PS, it only shows a sliver of the image at the top of the screen.  The only way that I can see more of it, is to zoom in, but even then, it will only show about half of the image, and the other half is just cut off and missing.  I've tried to open multiple images and they all come out looking like this.  I can't work on anything while the images are like this.  Please help.

Could you please post a screenshot taken at View > 100% with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible? 

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?

Yes, thank you!  Turning off the Graphics Processor worked.  Now I can see the whole image again.  I'm wondering why that just happened all of a sudden though?  I never turned that on.  So I'm wondering why it needs to be turned off. Also, will that effect anything negatively having that turned off?

Unfortunately this is no proper solution as it invalidates GPU dependent features (like the Rotate View Tool, 3D Features and some Filter acceleration for example) but it indicates problems with the GPU driver or the OS.
