How does one manually restart graphics drivers?
To reset the graphics stack in Windows, press Win+Ctrl+Shift+B.
If anybody is still searching for simple answer, then in Windows 7 it's as follows:
- Open Device Manager
- Expand Display adapters
- Right click on a graphic card and choose Disable
- Wait till the screen goes back and repeat step 3 with Enable.
That's it.
I had a similar problem on windows 8 and found that just changing the screen resolution and changing it back again resolved the corruption.
