sister in law has a problem on a MAC..

[Frame]

Hi, i know that many of you are Mac users, and my sister in law's boyfreind bought this Imac powerpc something, where upon he recently installed some OS called OSX leopard, in an effort to wipe the computer totally.

I do not know any version numbers or the type of the imac. But these can be obtained if they are essential.

The Mac ran smoothly for the last week or so, but now it has begun the behave weird as it is showing the following lines under the mouse cursor aswell at the top of all windows.. I'm suspecting something about the alpha channel on the mouse cursor and i presume the top of the windows may normaly be semi transparent..

anyway, any help will be more than welcome as i'm a complete MAC newbee..

here is the picture..

I'm hoping this to be something simple and not a prelude to a defect graphic card..

Cheers Frame...

Any help is appreciated.

Cheers Frame

Doesn't sound good ... I've never experienced anything like this myself but this sounds like it's a video card problem:

"Barcode" lines on mouse cursor and on desktop screen
