Just to add to the already fantastic news of losing my drive and the computer dying, I've just done the update for xbox live and it seems to have bricked my Xbox 360. I am now the proud owner of a bright white box with the three rings of death.
I guess I'll have to RMA that along with the memory for the new computer, and the old computers motherboard.
Random Good News: I rented Day Watch.
At least you didn't get three calls saying "you have seven days".
