Greetings Bob, It sounds like you have a problem with the AGP Video card. You might want to try shutting down the platform, removing the AGP card and then reseating it into the slot. If the card is covered with fuzz and cobwebs you should (using compressed caned air) blow out the crud, then reseat the card. Perhaps while you have the card out of the slot use the canned air to clean the AGP slot of anything that might have fallen in. If that doesn't fix your problem then AGP cards can be had on lemswap http://lowendmac.com/lists/swap.html Just post a "Wanted" or perhaps look for one on eBay.
