|"How about warranty repair?" ..... *roll eyes*|
There's at least two strikes against the OP.
Alienware has perhaps THE WORST warranty or customer support out of all ODMs out there. Secondly, the Area51 m-7700 is regrettably a notebook no one should ever purchase. It cost a pretty penny, yet it is so unreliable because of the notoriously problem-prone Clevo D900T motherboard that the model is equipped with.
Looks like it's time for a new motherboard. I have one sitting right next to me as I type this with a similar issue, that I'm debating getting rid of or replacing the motherboard.
Either way, this is my last Alienware purchase.
