Windows 7: Windows Configuration Every Morning Terribly Slow!

I just installed Windows 7 and like it for the most part. However, every morning it reconfigures itself, taking up to 10 minutes to boot. This is simply annoying. What's going on?

There is something not right - a clan install should take no more than 2 minutes from switching on to being totally usable.
Please check in the Event Viewer for any error messages - partiticularly Critical ones.
post back with the bare detail s of what they are.

In reconfiguring is it detecting all the hardware and installing drivers, if it is there is a good chance you need a new CMOS battery, if it's too weak it won't retain the settings.
