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.

office tech guys really know their way aroung an office network but give them an actual pc issue and they will run for the hills
