The issues you describe are driver related. Users are finding that they have to re-install 'some' drivers after the installation of the service pack although this doesn't affect everyone. You can get a copy of the service pack via certain links in this forum or choose to run the RC release. The RC release will place some writing on the desktop(saying 'Evaluation Copy') but I've got a cure for that so if you decide to get it let me know and I'll mail the cure to you.

Lastly, whenever I install a service pack I do it in a particular way... Fresh install of the OS, then service pack, then drivers and then your good to go! It's not critical to do it this way but IMHO the best way especially how this service pack is rewriting the Kernal.
