Whenever I start my iMac G5, I get a combination of moving black dots and the screen and some odd flickering. Imagine the Apple logo at startup with a breeze blowing in from the left blowing a wisp of pixels to the right. It'll continue flickering until it hits the desktop when it will eventually turn to a solid series of gradients with no way to see the desktop. At times the fan will kick up to full speed. Ideas?

Power Mac/iMac G5, Mac OS X (10.5.8)
