First off, I just wanna say I've been browsing these forums for a couple of months and its been very helpful to me. Ok, on with the problem. I tried googling it and couldnt come up with any solutions for my problem and i tried searching this forum and still no luck. I've come to notice that my iMac's screen shakes when I move my mouse over certain points of the screen. Its seems to be getting worse too. Is this a common problem? What can i do to fix it? Any help would be greatly appreciated. Also, it seems that the letters are a little blurry sometimes. I don't know if its just my eyes playing tricks on me eek because of the screen shaking, but that's just something else im gonna throw out there.
