Alienware makes a nice unit with high performance components. Before you go buying that new unit (which you want one way or another...lol). Make sure the current laptop doesn't have something simple causing the current failure (dead power supply, memory chip bad or needs re-seated, over heating due to clogged cpu exhaust port). If it's the motherboard....as you probably know, it's not worth fixing anymore. Replacement units have dropped in price dramatically over the past few years. Good luck.
