Plz help need opinions

OK so i assembled my first computer recently. And everything seems to be running fine. i am on it right now. But every now and then i get random black screens from my monitor. It doesn't effect what i am doing or anything just goes blank for a second and then back on. The monitor don't shut off when this happens. so

Is this really bad? is there something i can do? A Hardware problem/dying?

i also have a new graphics card coming in Tuesday, if it was you guys would you try and fix this before something bad happens, or should i wait for graphics card to come in. Run the graphics through that and see if the problem persists? Right now i am just running off mobo integrated graphics.

I have the msi 760gm-p34

any advice or info you could give me would be great.
