Hi
My MAC is quickly switching between the desktop and waht appears to be the screen saver.
Once the OS loads (OS X) i do not even get a chance to click on anything. The desktop appears for a second and goes to a blue (wall papper look a like) kind of widow. These goes back and forth on a loop for ever. When the desktop appears, by the type I point the mouse somewhere, the other quickly comes back.

My MAC is currently useless, please help.

G4 - DVI - 17 inch PowerBook - OS X.

Thanks

It sounds like you're auto logging into your user/admin account instead of going to the login screen. If so, that is not the safest way to use the OS on a daily basis.

I'm not the expert here, but if this was happening on my machine and I could not then log in to another user account to see if the problem is user specific, I'd see if I could isolate the problem first by getting some possibly corrupt user settings out of the way:

. reboot into single-user mode
. move user settings files (~/.* and ~/Library/*) into a temporary folder + tar that folder to ensure OS X does not find/use it
. reboot back into multiuser mode (OS X & apps would recreate their default settings at first launch) to see if that helped isolate the root cause...

Let's see if someone else has a better recommendation first...

I will try right now.

Thanks

Oh duh, a more prudent step 1 would be to boot from the system cd and run the disk utility tools from the system cd such as "repair disk permissions" and "repair disk" and do the h/w diagnostic test. Let us know the results.

I agree with rem. You have to check hardware first. If you follow general trouble shooting procedures you would first check hardware then software.
