I shut down most background programs, and I also restored to a system restore date that was prior to recieving the freezes. Sadly the computer then start refreezing but with much more frequency. I bought another copy and it installed flawless. It's been on for a day straight and no freezes. I think i was a victim of fraud where someone took a windows beta copy and inserted a bootloader. Looks very geniune and it said activated, it also updated, but alast it wasn't. Someone used a lightscribe burner to write on the dvd to make it look legit. This cost me major dollars, so beware of scams. You are not immune on ebay.
