Green square glitches and errors on my screen

Usually seems to happen after playing BF4, but sometimes just randomly while my PC is on, picture below.

Any idea's what it is and what's causing it?

Thanks in advance

Turn down the graphics settings on your video card.

Something related to your video card or drivers most likely. Is it much worse when playing BF4?

You can restart the display driver instead of rebooting. in Win7: right click Computer (on desktop) -> Properties -> Device Manager (left menu) -> display adapters -> double click your display adapter -> driver tab -> disable. Screen will flicker and probably change resolution. then choose "enable" button to re-enable the driver.
