I must respectfully disagree with bassfisher. Based on countless thousands we've helped to
Clean Reinstall - Factory OEM Windows 7 it's best to go with the
drivers given by the installer and quickly updated via optional Windows Updates when you enable
Automatically get recommended drivers and updates for your hardware.
This is not XP. MS spent close to a billion dollars getting the drivers into the installer and via Updates, even paying manufacturers to build them under WHQL so they wouldn't hold out and MS would have them first.
There is a one-in-a-million possibility a
driver in the Updates package caused this problem but it could also be an Update itself. This is why as it says in the tutorial it's best to break the Updates into smaller packages and observe their install just like Program installs to watch that they install correctly and gauge performance after each install.
What I would do now is
System Restore to before the Updates were done, then install them in smaller groups monitoring closely each one's progress. If the problem reoccurs then Restore to before that group and install those Updates singly to find the problem update, post it back here and in our Updates forum. MS also provides free email support for Windows Updates on its website.
If you didn't follow the Best Practices for Windows 7 install in
