first off dustin, welcome to techspot.
It does sound like a video problem...
Before we can help you out..we need a bit more info.
First off, have you made anymjor changes to you PC? Or have their been any problems before this happend? (flickering screen etc etc)
Replacing a video card is not hard at all, but we need to determine if your PC used an actual video card, or the video output is built into your Motherboard.
If you could tell us you PC make, Model, and some simple hardware specs, including you motherboard, and video card (if you use one)
If you dont know how to get them (specs), dont panic, its not that hard. You should consult this post found
here
Post back with your specs, and we can go from there....
Good luck
Sean
