Windows 7 Professional issues

Five days ago, when I turned on my Dell Latitude running Windows 7 Professional, the upgrade screen came on and said I had 144 updates, not to shut down computer until completed. So I didn't. When it was done it shut down. Then when I turned on it went to a screen that says load Windows normally or Use repair tool. I chose load windows normally. The system went through the normal boot but then went back to the screen that says load normal or use repair tool. I chose repair tool this time. This time it said that it could not find windows.
I reset the bios to defaults for everything.
Reinstalled Windows 7. This worked for about a day. Everything seemed to be ok. So I shut down the computer until the next day. When I turned it on it went to the 144 updates again and again I went through everything that I did before, again.
What is going on?
Does anyone have an answer?

I would start with manually managing the updates--install 1-5 of them at a time.
Also, avoid the driver updates from M$ and instead get third party updates directly from the hardware manufacturer (e.g., video drivers--ATI/Nvidia).

A while back I had some weird nonsense occur due to a .NET update causing my systems to take a VERY long time to bootup. It took me days to figure it out by process of elimination.

Hope that helps...

Everything is here to get and keep a perfect Clean Reinstall Windows 7 based on tens of thousands of installs we've directly helped with here, and which has been used by 1.5+ million consumers without a single complaint.

Be sure to read the steps printed in red about drivers in a driver-complete OS so you don't use XPired methods. Not one of the 1.5 million has complained about using the drivers Win7 provides.
