Computer takes a long time to start

From virus infection to conflicting startup items to multiple third-party security products, there are several reasons that can cause your computer to start slowly. Norton can help you with some of the causes and reduce your computer startup time.

Before you follow the steps, make sure that you get your PC tuned up using Norton's performance features. For more information, read Fix computer slow problems.

STEP 1

Manage startup items

    You may have many programs loading at startup that can slow down the startup process. With Norton's Startup Manager feature, we can help you manage your startup programs and reduce the startup time

  1. Start Norton.

  2. In the Norton window, double-click Performance, and then click Startup Manager.

  3. In the Startup Manager window, under Delay Start, select the program that you want to delay.

    If you are not sure which programs to delay, review the result under Resource Usage. If a program has high resource usage, we recommend that you add it to Delay Start.

  4. Click Apply, and then click Close.

STEP 2

Uninstall any non-Norton security product

    Each security software is designed to work independently on a computer. Multiple security solutions on a computer are generally not optimized to work together, resulting in performance degradation.

  1. Press the Windows + R keys to open the Run dialog box.

  2. Type in the following text, and then press Enter.

    appwiz.cpl

  3. In the list of currently installed programs, select the non-Norton security product, and then click Uninstall or Remove.

  4. Follow the on-screen instructions.

  5. When the uninstall completes, restart the computer.

    You can also read the program documentation or contact the program manufacturer for instructions to remove a non-Norton security product from your computer.

STEP 3

Download and run Norton Power Eraser

    Your computer may have a Rootkit and that can slow down the computer startup. We suggest that you run a scan with Norton Power Eraser to remove any infection.

  1. Download Norton Power Eraser.

  2. Do one of the following depending on your browser:

    • For Internet Explorer: Click Run.

    • For Firefox or Safari: On the top-right corner of the browser, click the Download option to view the downloaded files, and click the file that you downloaded.

    • For Chrome: On the bottom-left corner, click the file that you downloaded.

  3. If the User Account Control window prompts, click Yes or Continue.

  4. Read the license agreement, and click Accept.

  5. In the Norton Power Eraser window, click the Scan for Risks icon.

  6. By default, Norton Power Eraser performs a Rootkit scan and requires a system restart. When you see a prompt to restart the computer, click Restart. If you do not want to include the Rootkit scan, go to Settings, and uncheck the option Include Rootkit scan (requires a compuer restart).

  7. After the computer is restarted, the scan starts automatically. Follow the on-screen instructions.

    Wait for the scan to complete.
