Since about a month ago, I've had to deal with my system freezing for about 5-6 minutes shortly after start up. I can move the mouse pointer but cannot access the Start Menu or any of the icons in the system tray. When I try to do that, I get the hourglass next to the pointer. I've pressed CTRL+ALT+DEL but even that won't bring up the Task Manager until the "freeze" is over. When the Task Manager finally comes up, it'll show the CPU usage at 100% very briefly before it drops off.
I've checked the logs on Norton Firewall and it seems to be related to updates.microsoft.com.
Can anyone shed some more light on this?
