    From some days i notice that while a move some windows around the screen, or using iPhoto i get kind of like an horizontal line across the screen

    kind of like when when with old not LCD TV you use a microwave or some kind of interference

    grafic card is: ATI Radeon HD 5750

    Could be either the LCD or the GPU failing. You can try reinstalling OSX, but if it still occurs, then you've likely got a hardware fault some place. Could be as simple as the cooling system being clogged with dust causing something to overheat, or could be a system chip somewhere beginning to fail.

    If you still have AppleCare this is a two-step process:

    Figure out if the cause is hardware or software

    If it's hardware, make sure you can reproduce the symptoms, then bring it to Apple immediately.

    If you have AppleCare get on the phone right now and call them, your issue will be covered. Be prepared to take the machine in for service. So BACKUP prior to taking it in and ensure the backup is sound.
