Here's the skinny: I'm running XP on a HP Pavilion Media Center box. I just replaced a failing HDD and am trying to install XP back on it. I initially got it to work and was having trouble activating XP. I used a disk that originally came with the system. It would not connect to the activation server, even though it could load web pages. First...is the activation thing a new thing? I've reformatted and reinstalled windows more times than I can remember and I've never had to activate it this way (always have entered the code during setup). Second...I've tried to rerun setup with another disk (one I just used within the past month to setup another computer), and I keep getting a BSOD during setup, right after it loads the drivers and says "Windows is starting". Now I'd like to reformat the *$&%# thing and rerun setup with a different CD, but I can't get setup to work, even though I'm using a different CD...it keeps puking at that same spot. Any ideas would be most appreciated!
