This has happened quite a few times since install (2 days ago). When using vista (dual boot) there are no freezes, so i doubt its a hardware issue. Also yet to note a freeze when not browsing/ connected to net. Everything freezes, and i have to hold the power button to restart. this has happened with firefox, chrome, and ie8. I have seen examples of this in other forums, but no definitive answers. any help would be really appreciated.
