How to Fix Windows Vista Errors

Run Vista Startup Repair
1. Insert your Vista installation disc into your CD- or DVD-ROM drive and then restart your computer (click the 'Start' button, point to the arrow in the bottom-right corner and click 'Restart').
2. Pick a language from the list, click 'Next,' click 'Repair your computer,' choose the operating system to repair and then click 'Next.'
3. Click 'Startup Repair' and follow any instructions and prompts that appear as the repair process attempts to fix problems. This process is meant to fix errors such as missing system files that might be interfering with your startup.
Troubleshooting Blue Screen Errors
4. Turn off automatic restart. Click 'Start,' right-click 'Computer,' select 'Properties,' click 'Advanced System Settings,' click 'Settings' under 'Startup and Recovery,' uncheck 'Automatically Restart' under 'System Failure,' and then click 'OK.' This will prevent your computer from restarting on its own the next time it has a blue screen error.
5. Record all the error information the next time your computer has a blue screen error. The blue screen will contain information about the error, such as an error code and other technical information.
6. Go to Microsoft's Support website (see Resources) and search for information to fix your specific blue screen error. Microsoft has guides and help for fixing many specific blue screen and system errors.
Other Steps
7. Run Windows Update. Click 'Start,' 'All Programs' and then 'Windows Update.' Click 'Install' to install any new updates that your system detects.
8. Run Windows Defender. Click 'Start,' 'Control Panel,' 'Windows Defender' and 'Scan,' and remove any spyware or malware threats that the scan detects.
9. Update or roll back drivers. Click 'Start,' right-click 'Computer,' click 'Manage' and click 'Device Manager.' Double-click on a device category, right-click on a hardware device listed under the category you selected and choose 'Properties.' Click the 'Driver' tab and then click 'Update driver...' to update the device or 'Roll Back Driver' to have the driver revert to an older version.
