When the computer crashes but you can’t fix the problem, using System Restore is the most appropriate method. The System Restore function on Windows 7 allows the computer to return to a time before the error occurred. You can use System Restore in the following situations: getting an error while installing a new operating system, new hard drive or software.
Steps
Performing System Restore

- If the computer won’t boot into Windows, read the troubleshooting section.
- Check the “Show more restore points” dialog box to see all available restore points. There may not be many options because Windows automatically deletes the restore point to make room.
- Each restore point will have a short description of the change that made the point.
- Any programs installed after creating a restore point will be removed, while those that are removed will be reinstalled.
- If System Restore has made your computer worse or you want your computer to return to an unrecovered state, you can cancel the most recent restore by running the System Restore tool again and then selecting “Undo System Restore” (Uninstall System Restore).
