If you just bought it you showd have a warranty...go back with it at the shop and they will send it for repair. It is too risky to do it yourself and pointless if you have warranty. Or you could try SEUS(easyest, but i don't recomend it). Cheers. Ah yes and do serch the forum as there are step-by-step tutorials that can help you in the case you want to do it on yourown.
