Windows 7 / Getting Started

Check Your Hardware

You can use the following hardware-related techniques to recover from problems that cause Stop messages.

Restore a Previous Configuration

If a Stop message appears immediately after you add new hardware, see if removing or replacing the part and restoring a previous configuration resolves the problem. You can use recovery features such as Last Known Good Configuration, Driver Rollback, and System Restore to restore the system to the previous configuration or to remove a specific driver.
