This computer freezes at least once a day, and thats a good day!! The norm is two or three times a day. My Toshiba laptop has Vista Home Prem too and never misses a beat. I don't believe Windows 7 will fix it. It must be the HP motherboard design that makes this an unstable system. I loose work constantly with this pc. It seems to be particularly bad anytime you try to save a file to the hard drive or thumb drive; it freezes during the save. The only option is to reboot. HP is offering memory upgrades and price specials on the e9180 Pavilion Elite. They want to get rid of this junk. Like my childhood game where the saying was "No tag backs". That's HP's attitude. Do yourself a favor and don't buy HP current products. They have gone straight down hill.
