Why are you keeping this machine?
Bought new in August, Windows 7, 64-bit system. Hardly a day goes by that the computer doesn't completely freeze. Not even the nicety of the blue screen of death---just blank. Frozen. Inelegant shut-down. No commonality in tasks being done at the point of death. It's an annoyance when I'm in the midst of reading email. It's catastrophic when I'm in the midst of creating a work document.
