Hello, I've got a really strange problem here.
Windows 7 Professional x64 edition is installed on a computer. During the installation, every time it went to restart the system would hang immediately; I had to do a hard reboot to continue the installation.
Now Windows 7 is installed, and still hangs on reboot. When I choose Restart, the system shows the shutdown screen, goes black, and hangs. After some time waiting it never reboots and I never see the BIOS screen. However, if I choose "shutdown", it works perfectly.
Also, when I force it to reboot, the system does NOT give me the message that it wasn't shut down correctly. I've reinstalled the system twice. All drivers are installed correctly, and Windows is completely up to date. I even updated the BIOS to the current version.
It's also worth noting that I also booted this machine using a Fedora Linux Live CD, and it restarted without a problem.
Any ideas would be very helpful. Thank you!
