Windows 7: Logoff/sleep freezes

I used the upgrade process in Windows 7 to go to Windows 7 from Vista. Everything works well except when I try to sleep (close the lid on laptop) or logoff. The system freezes sometimes and I have to force the system down with a power off.

It appears that the first attempt usually works. The next logoff/sleep is when the problem appears.

I have removed all third party software and the problem still occurs.
I updated to latest bios from Compaq for CQ70-134CA Laptop. No luck.
I changed the Power Plan to disable the sleep mode when the lid is closed. The system still freezes when the system goes into sleep mode after the set timeout.



I changed the Power Plan so that the hard drive does not go in power saving mode. Finally the system is stable but never goes into sleep mode.

Does anyone out there think that the hard disk going into Power Saving mode is the cause of this problem?
Any ideas out there?

I decided to go with a clean fresh install and wiped out the NTFS active partition. I then reinstalled Windows 7 as a Custom install.

Everything works great. The upgrade install must be flawed and somehow caused the freeze to occur.

Exact same problem here. I spent a great deal of time eliminating programs that start up with Windows, but to no avail. Usually, logoff would eventually take place after a very long time, but sometimes had to press power button to regain control of computer.

Solved the problem by doing a clean install. It seems that there is a problem in the installation code by which Vista is upgraded to Windows 7.

For others out there the best way to upgrade is:

Boot system on old OS (Vista) and browse Windows 7 DVD.
Run Easy Transfer and save all of your user data to a USB drive.
Reformat old NTFS partition.
Reboot from Win 7 DVD and then install.
Use Easy Transfer again to reload old user data stored on USB drive.

Im having the same problem after closing lid of laptop, when i come to restart i get the log on screen but then just a black screen i have to reboot after a forced shut down to gain control. i did a clean install from vista so upgrade not the problem this time.

I have never had good luck with an upgrade install in transitioning to any new Microsoft OS out there. Clean is always the way to go. You just spend too much time troubleshooting issues you can never solve otherwise.
