After an automatic windows update 4 days ago, my Dell Inspiron 1501 keeps saying it is configuring the third of 3 updates, then immediately shuts down, reboots, and goes through the same loop again and again. I have tried system repair and system restore, but neither fixed it. I saw on some geek sites that this is not an uncommon problem, but the suggested fixes mentioned above didn't solve it. Any suggestions would be very welcome.
