The original hard drive failed and I had it replaced by an apple certified tech last week. He also installed OS 10.4. The machine worked fine for a few days. But now, when I press the power button the startup sound chimes but still have a blank screen with no icons or desktop image. I can insert a music CD and then play it with itunes but I can't see anything. The screen lights up but it does display anything. What can I do?
