I have run into a very mystifying and frustrating problem (to me). I have just installed a fresh copy of Windows XP home edition on a new hard drive. Everything goes fine and when it is installed I start the update process. Windows Update installs its latest version, then I go through it and get all the security updates it recommends. After those are done, it next recommends SP 2 - which I had running just fine on the same machine on the old HD. That also installs fine.. now the fun ends.
After SP2 is installed, and the system is up and running, any web page I browse to causes my computer to lock up and then reboot. After playing with the security and other settings I have narrowed it down to the entry in:
Internet Options : Security Tab : ActiveX Controls and Plugins
specifically the option for
Binary and Script Behaviors
If this is enabled then any page with any script (including running windows update) will cause my computer to lock up, sit for 3-4seconds, then reboot. No warnings, no errors.. I can move my mouse, but cannot select any window or start menu or taskbar item. I cannot alt-tab or ctrl-alt-del.
I am also unable to open the Security Center in the control panel (same behavior), and when I click on the keys for Activating this copy of XP, the activation window frame comes up but doesn't redraw the window (so you still see the stuff behind), it locks, and reboots.
I cannot seem to find any information on this type of behavior anywhere. Does anyone have any ideas?
