I recommend you remove your hardrive and get a new notebook. Notebook motherboards are proprietary. You'll be lucky to find your model number; you'll pay too much for a used board with limited warranty. If a new one is available, by the time you pay for installation, you could buy a brand new notebook. Here's one example: http://www.bestbuy.com/site/Lenovo+-+Laptop+-+Black/4592602.p?id=1218493899010&skuId=4592602
(amd). An asus model with Intel core i3 cpu is about $50 more, but the link didn't work.
