    I recently sold my Blue & White G3 and a 19" Sylvania CRT monitor. A couple of weeks later, the buyer called me with this problem. The screen is full of vertical white lines. The mac never had this problem for the 5 years that I owned it. I told him to make sure the G3 is ventilating properly (i.e., give the back fan room) and to try a different monitor. He tried connecting a different monitor and still gets the white lines.

    Now I'm clueless as to what could be causing the problem. The G3 is running mac os 10.3. I can ask for the version of 10.3 if necessary.

    Can anyone help with a fix for this?

    It's looking like the problem is the video card. Can anyone recommend a good replacement PCI video card for B&W G3?
