File Checker from CMD

To start the System File Checker follow the below steps:

Click Start>All Programs>Accessories, right click on the Command Prompt option on the drop down menu which appears, click on the Run as Administrator option.

a. In the Command Prompt window, type: sfc /scannow,

b. Press Enter.

c. You’ll see “the system scan will begin”.



The scan may take some time and windows will repair/replace any corrupt or missing files. You will be asked to insert your Vista DVD if it’s needed.


If the above step did not fix the issue, try restoring the system to an earlier point prior to windows update when everything was working fine.

To restore the operating system to an earlier point in time, follow these steps:

Click Start, type system restore in the Start Search box, and then click System Restore in the Programs list. If you are prompted for an administrator password or confirmation, type your password or click Continue.



In the System Restore dialog box, click Choose a different restore point, and then click next.



In the list of restore points, click a restore point that was created before you began to experience the issue, and then click next.

Click Finish.

If all the above steps did not fix the issue, try startup repair. Refer the steps below in order to do a startup repair:

If you have a Windows Vista installation disc, you need to restart (boot) your computer using the installation disc. If you do not restart your computer from the disc, the option to repair your computer will not appear.

If you have a Windows Vista installation disc:

1. Insert the installation disc.

2. Restart your computer.

Click the Start button, click the arrow next to the Lock button, and then click Restart.

3. If prompted, press any key to start Windows from the installation disc.

Note: If your computer is not configured to start from a CD or DVD, check the information that came with your computer. You may need to change your computer's BIOS settings. For more information, see BIOS: frequently asked questions.

4. Choose your language settings, and then click Next.

5. Click Repair your computer.

6. Select the operating system you want to repair, and then click Next.

7. On the System Recovery Options menu, click Startup Repair. Startup Repair might prompt you to make choices as it tries to fix the problem, and if necessary, it might restart your computer as it makes repairs.


If Startup Repair is a preinstalled recovery option on your computer:

1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.

Click the Start button, click the arrow next to the Lock button, and then click Restart.

2. Do one of the following:

• If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you will 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.


3. On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then press ENTER. (If Repair your computer is not listed as an option, then your computer does not include Startup Repair as a preinstalled recovery option.)

4. Select a keyboard layout, and then click Next.

5. Select a user name and enter the password, and then click OK.

6. On the System Recovery Options menu, click Startup Repair. Startup Repair might prompt you to make choices as it tries to fix the problem and, if necessary, it might restart your computer as it makes repairs.
