Flickering monitor and odd orange pixels.

[Dranu]

Lately my monitor will randomly flicker black on all or partial horizontal wide areas across the screen. Having Windows 8.1, it will also be inclined to go all black occasionally when I enter the start/apps screen. Also, occasional red/orange pixels will show up and flicker slightly, but are not stuck on the screen but rather whatever particular image happens to be on the screen (for instance, if you scroll down, the pixels will only stay with that image; not fixed in one place on the screen). Likewise, the monitor will sometimes flicker in just part of a website, but the toolbar, for instance, will remain stable.

I have tried updating my graphics drivers, changing the AVI cords, and switching monitors, and it still will happen occasionally. Any idea what the cause is? Is it my GPU?

I have a fairly standard modern gaming computer with a factory overclocked NVIDIA GPU (no overclocking on my end) and a Samsung monitor.

If the problem is consistent on different monitors and cables, that only leaves the graphics card.
