No it is not under warranty as I bought it in 2004. I don't want the cost of going to a dell svc center or any other svc center if it is something I could probably do myself. As it is an old computer it really isn't worth taking it somewhere to pay hundreds of dollars for them to look at or fix.
Go to ebay website, there's Dell 6000 motherboard sell it cheaper or some Seller ,they can
repair your MB with warranty
