OK Jeff. I'm glad i'm not alone here.
First, I must say that I still have 3 PC with problems.
However, the last one (the 4th one) (more info about how I proceed with Windows 7 installation here: http://social.answers.microsoft.com/Forums/pt-BR/w7hardware/thread/2a9360b1-522e-46fb-ade5-89d4411e4876)
never give problems till now. It's starting to show the very same issues.
Some BAD news: I found a single Windows Vista installation here in my network, that have AutoCad stop at startup too. However, Vista do not have "devices and printers" window, so... i'm confused. But the symptoms are the same.
Things I do to make the "devices and printers window" get populated again:
- 2 or 3 reboot's will do
- Reboot with that window open trying to find devices...
- Uninstall the Network Card and reboot (reconfig if necessary after).
Known symptoms:
"Devices and Printers" window is empty
Office Excel freeze just changing a color element
AutoCad stop responding when starting - freeze completely.
Jeff: You could try something here:
I'm almost sure that the problem is related with Network card - hardware or software issue.
Please, do the Uninstall of the Network Card in Device Manager. Reboot the Notbook, it will reinstall. After that the "Devices..." window should be not empty. Do you need help with that?
Then post you result's.
Thanks. We will be in touch here.
