I finally finished building my computer for college and everything is finally working right. I just have one small problem with my monitor screen. Just about every 3 seconds or so, a wavie line will start at the bottom of the screen and slowly move up. Another one over and over again, all the time. I have a Viewsonic flat-screen P95f+. Is this a resolution problem or graphics card problem maybe? I have a Radeon 9800 Pro 256 MB by the way. This seems like it might be a common problem so could anyone give me some help as to how to solve it?
