Dunno, I started watching during BGC, but slowly slowed down, then picked back up on Halo 3. Didn't watch much of the Halo Reach Season/Series. As far as your computer issues go, maybe you could remove the hard drive and take it somewhere to see if you can get the files on there off. Or you can go get your whole computer fixed...?
The computer was always slow as forget, but I guess sometime after moving to this computer it simply lost it. So... I got a ton of files on it, but transfer rates are slow if I even get on it... I would like full access, but I can't even be bothered to turn it on or take the harddrive out... :S
