Desktop display moves all over the display when the mouse is used
Desktop moves all over the display when the mouse is moved. Not sure how to explain this. Working on imac, everything normal, click the mouse to open something then all of a sudden, the entire desktop display screen becomes "unhinged" and started moving back and forth as the mouse is move as if it reset itself in system profiles to a lower resolution. Tried resetting monitor in system profile back to higher res, tried mouse settings. Shut down, unplugged, boot back up. And problem remains. Nicole

I know you've already visited the Mouse options in Preferences, but did you check to see if the "Zoom Using Scroll Wheel" box is checked? If it is, uncheck it.
Or on the keyboard, try pressing these three keys at the same time: Option / Apple (Command) / 8. That should do the same thing.
I hope that helps.

the new mouse is delicate and sensitive, both of which can be turned down in system preferences. the "gestures" on the mouse are such that the screen moves when you swipe your finger. Gestures can also be turned off in System Preferences under Mouse
you have done is accidently magnified your screen slightly. To correct
this hold down your ctrl key and move your finger back on the mouse. You can switch this feature off by going to system preferences then universal access and switch off zoom. Hope this helps.
It sounds like you have zoomed in on your screen image, so your screen is showing you only a portion of your desktop. In this situation, you move to a different region of the screen using the mouse cursor, as you describe.
You can zoom back out by holding down the CONTROL key while rolling your mouse's scroll wheel (or scrolling with two fingers on the surface of an Apple Magic Mouse).
Since you are able to see your mouse pointer move, the display is refreshing so the problem is with something other than the graphics card. Generally software / OS related.
So assuming you aren't experiencing a hardware failure try the following...
Boot from the CD the computer shipped with.
Insert CD and restart the computer holding the "c" key Your computer should boot from the CD
If so run disk utility from the CD and repair the disk as well as permissions. If there are any errors repair again.
this is successful your computer "should" be repaired. If it is still freezing, use your CD to perform a Archive and install which
should keep all your personal settings and installed software intact.
