Click the Tools tab, and then, under Error-checking , click Check now. To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors.
Otherwise, the disk check will report problems but not fix them. To perform a thorough check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the drive itself, and it can take much longer to complete.
To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors. In the search box, type Memory , and then click Diagnose your computer's memory problems.
Choose when to run the tool. If you choose to restart your computer and run the tool immediately, make sure that you save your work and close all of your running programs. The Memory Diagnostics Tool will run automatically when you restart Windows. The following tools can help you uninstall or roll back software changes, repair Windows startup files, and restore your system from an earlier backup. If none of those suggestions fix the problem, you can reinstall Windows 7.
Several of the following tools are located on the System Recovery Options menu. This menu is preinstalled on your computer's hard disk, and is also on the Windows 7 installation media. If you use a Tablet PC or other computer with a touchscreen, you might need to connect a keyboard and mouse in order to use Startup Repair and the other tools in the System Recovery Options menu.
For more information, see What are the system recovery options in Windows 7? If Windows 7 came preinstalled on your computer, your computer manufacturer might have included other recovery options. For more information, refer to the documentation that came with your computer, or go to the manufacturer's website. For example, if a corrupted video card driver is preventing Windows from displaying, or if a program runs as soon as you start Windows and can't be shut down, you can start Windows in safe mode before the driver or program starts and then try to fix the problem.
Click the Start button , click the arrow next to the Shut Down button , and then click Restart. Startup Repair can detect and fix certain types of system problems that might prevent Windows from starting, such as missing or damaged system files. Startup Repair is designed to start automatically if certain system problems are detected, but you can also run the tool manually. Remove all CDs, DVDs, and other media from your computer, and then restart it using the computer's power button.
If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer. If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to repair, and then press and hold F8.
On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer , and then press Enter.
If Repair your computer isn't listed as an option, then your computer doesn't include preinstalled recovery options, or your network administrator has turned them off.
If your computer's system is severely damaged and you can't access the System Recovery Options menu on your computer, you can access it using the Windows 7 installation disc or a USB flash drive, or using a system repair disc if you created one earlier. Insert the Windows 7 installation disc or USB flash drive, or a system repair disc, and then shut down your computer. On the Install Windows page, or on the System Recovery Options page, choose your language and other preferences, and then click Next.
If neither the Install Windows page nor the System Recovery Options page appear, and you're not asked to press any key, you might need to change some system settings. To learn how to do this, see Start your computer from a Windows 7 installation disc or USB flash drive.
If you're using the Windows installation disc, click Repair your computer. Select the Windows installation you want to repair, and then click Next. It's just like running System Restore normally, with one exception: System Restore can't create new restore points in this mode, so you can't undo a restore operation.
However, you can run System Restore again and choose a different restore point, if one exists. If your computer's system is severely damaged and you cannot access the System Recovery Options menu on your computer, you can access it using the Windows 7 installation disc or a USB flash drive, or using a system repair disc if you created one earlier.
If you've used Windows Complete PC to create a system image backup as part of your backup plan, you can use the system image to restore your computer. A system image is a copy of the partition on your hard disk that contains Windows. It also contains everything on that partition on the date you created the image, including Windows, your programs, and user data—such as documents, pictures, and music.
You need to have created a system image beforehand to use this option. When you restore your computer from a system image, the contents of your hard disk are replaced with the contents of the system image.
This means that any changes you've made, programs you've installed, or files you've saved after the system image was created will likely be lost unless you have a recent backup of your data.
Restore from a system image using the Windows 7 installation disc or a USB flash drive, or a system repair disc. If you can't access the System Recovery Options menu on your computer, you can access it using the Windows 7 installation disc or a USB flash drive, or using a system repair disc if you created earlier.
If you can't recover Windows 7 in any other way, you can reinstall Windows 7 using your original Windows 7 installation disc or setup files. Reinstalling Windows 7 will delete any programs you've installed and will restore the default Windows settings.
You'll need to restore your user files, and reinstall any programs you've installed using the original installation discs or files. To format your hard disk during Windows 7 installation, you'll need to start your computer using the Windows 7 installation disc or a USB flash drive.
Turn on your computer, insert the Windows 7 installation disc or USB flash drive, and then shut down your computer. Not an IT pro? Resources for IT Professionals. Sign in. United States English.
