When I turn on my iMac on the screen flickers and has strange lines go through it. Sometimes it freezes on startup and the fans go at 100% so I just force it to be shut down. When I am able to get through the startup and into my computer, its not long before the screen goes slightly fuzzy and have weird colours and lines and the grey notice in several languages appears telling me to restart. Once restarred, its just a repeat of this I said before. Please help.

iMac G5, Mac OS X (10.4.11)
