Blank screen (backlight on) after idle and alt-tab

I have a problem where occasionally I get a blank screen with no graphics but backlight after I turn on my screen after idle, or when I try to alt-tab out of a program.

My specs are a Toshiba Qosmio X870 with GeForce GTX 670M and Intel HD 4000.

Any suggestions are appreciated. I can't figure out what is wrong for the life of me.
