HP PCs - The Computer Restarts Unexpectedly (Windows 7)

This document pertains to HP and Compaq computers with Windows 7.
If Windows 7 suddenly starts without warning, or restarts when you try to shut it down, it may be caused by one of several issues. Windows could be set to restart automatically when certain system errors occur. This feature of the Windows 7 operating system can be disabled. A BIOS update can also resolve the issue. Use the information in this document to resolve issues with the computer restarting unexpectedly.
 note:
In addition to the steps in this article, updating video card drivers is known to resolve many of the problems that can cause the computer to restart.
Windows restarts for no apparent reason
If your computer restarts unexpectedly, follow the steps in this section until the problem is resolved.
Step 1: Disabling Automatically restart option to view error messages
Many hardware driver or operating system errors will cause the computer to display a specific error message before stopping the operation or shutting down the computer. However, an error may cause the computer to stop operating, but it will not display an error message if the Automatically restart option is enabled. Disable this option to allow the computer to display the error message.
You can prevent the computer from restarting by turning off the Automatically Restart option using one of two options. Follow the steps in the appropriate section.
Step 2: Checking for failed hardware
Hardware problems can cause the computer to restart unexpectedly. For more information about checking for hardware problems, see HP Desktop PCs - Testing for Hardware Failures (Windows 7) or HP Notebook PCs - Testing for Hardware Failures (Windows 7 and Windows Vista).
 note:
Failed hardware is usually caused by increased heat inside the computer. Over time, cooling areas can become clogged with dust buildup causing temperatures inside the case to rise. For more information, see Reducing Heat Inside the PC (Notebook PCs) or Reducing Heat Inside the PC (Desktop PCs)
Step 3: Updating the BIOS
A BIOS update can resolve issues with the computer shutting down unexpectedly. Follow the steps in the following sections to use HP Support Assistant or to check for a BIOS update at the HP website.
Step 4: Performing a System Restore
If an issue has begun recently, restoring the computer to a point before the problem began can resolve the issue. For more information about using system restore, refer to Restoring Windows to a Previous Point.
Step 5: Recovering the computer
If the troubleshooting fails to resolve an issue, recover all software on the computer back to its original configuration using HP System Recovery. For more information, see Performing an HP System Recovery in Windows 7.
