In the UK we've got Statutory Rights that go on top of merchant guarantees:
'Statutory rights are controls placed into a contract by the government when anything is bought or sold. Acts such as the Sale of Goods Act 1979 fall within this category and concern issues such as quality and accuracy of description which are intended to protect the rights of buyers. So, for example, if you are buying food with a label saying "no artificial colours or flavorings" then you are entitled (according to your statutory rights) to expect a product that fits that description.'
Basically if an item does not perform how it is intended, without outside interference, within it's expected lifetime then you should be able to, by law, take it back and get a replacement or refund. Even if the store says they have a 14 day return policy. Your PC, as a whole, does not work as intended even though the parts seem to work.
If you live in the UK, ask at any citizens advice for free help, they'll be able to tell you what you can do. Hey it's gotta be worth a try!
I don't know what happens in the US, I'm sure there must be something similar, but it's remarkable how many people don't know about their own rights.
