Hardware Troubleshooting for Restart, Hang, No Display issue.

 Hardware Troubleshooting for Restart, Hang, No Display issue.           
Shutdown problems in Windows 7 can be caused by many factors, just like earlier versions of Windows. These included: a damaged exit sound file; incorrectly configured, damaged, or incompatible hardware; conflicting programs, or an incompatible CODEC, damaged, or conflicting device driver. Windows 7 shutdown issues mostly center around a very few issues, especially legacy hardware and software compatibility issues.

Currently, the leading cause of Windows 7 shutdown problems is hardware incompatibility, including driver issues.  However, it is impossible to list every possible hardware or driver issue individually. My best advice is: Check all drivers for all hardware devices to ensure that they are the current best for Windows 7.

REBOOT INSTEAD OF SHUTDOWN
Most Win XP shutdown problems reported thus far have been that it reboots when shutdown is attempted. This may be a global symptom emerging from several distinct causes, because, by default, XP executes an automatic restart in the event of a system failure. But Thid rarely happens with Window 7.

Disabling the “restart on system failure” feature may permit the exact cause to be isolated: Right-click on My Computer, click Properties, click the Advanced tab. Under “Startup & Recovery,” click Settings. Under “System Failure,” uncheck the box in front of “Automatically restart.”

You may also check the following options in a Windows 7 based PC.
  • Whether or not APM is enabled.
  • USB Connections.
  • “Wake on” power settings Power-management settings.
  • Hidden “wake on” power settings.
  • Logitech Internet Keyboard can also cause this problem. 
  • Logitech MouseWare 8.6. Windows reboots when shutdown is attempted. The software caused a BSOD with KBDCLASS.SYS. Removing the software solved the BSOD the problem.  
  • Webstar DPX USB cable modem. In the one case known to me, the problem was solved by switching the modem’s connector from the USB 2.0 port on the motherboard to the USB 3.0 PCI card.
