I've had my laptop for a year, and it is currently running Windows 7 Professional. I recently had a problem that causes the black screen randomly with the screen turned on (I mean everything is black and I can't see a thing, but can still see the light of the LCD screen). This often happens when I open/close a window, browsers web example, the records, or even during the boot. I want to know how to solve this problem and if the upgrade to Windows 10 works for her.

Hi Haolin,

Thanks for posting your query in Microsoft Community.

I do not understand that the screen goes black randomly, and I'll be happy to answer your query. Let me ask you;

  • What is the brand and model of the computer?
  • Remember to no particular change in the computer before the show?
  • When was the last time it worked?

Video card problems are the most common cause of this problem.

Try the following troubleshooting procedures in the order. If the steps described in the first procedure does not resolve the problem, continue to the next procedure.

Step 1: Reinstall your video driver

  1. Right click on the bar tasks and then click Start Task Manager.

  2. Click on the processes tab, click explorer.exe, and then click end process.

  3. Click file, and then click new task (run).

  4. In the text box open, type explorer.exe, and then click OK.

  5. Click on the Start button , go into the Device Manager in the start search box, and then, in the search results, click on the peripheral Manager.

  6. Double-click on display the cards, right click the display device, click Update driver software, and then follow the steps in the wizard that appears. You can also visit the website of the manufacturer of the computer support and install the latest available graphics cards for the same model of computer you have.

Note: After the driver is re-installed, you may need to restart your computer to complete the installation. You may also need to adjust the resolution of the display to its previous value. For more information, see change your screen resolution.

Step 2: Search for registry problems

  1. Right click on the bar tasks and then click Start Task Manager.

  2. Click on the processes tab, click explorer.exe, and then click end process.

  3. Click fileand then click new task (run)

    In the text box open, type explorer.exe, and then click OK.

  4. Click on the Start button , type regedit in the search box, and then, in the search results, click on regedit.exe.

  5. Navigate to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

  6. Click to select the WinLogon key and then in the right pane, click on Shell. The value of shell in the data column must be explorer.exe. If the value of Shell is not explorer.exe, double-click Shell, and then, in the value data text box, type explorer.exe, and then click OK.

  7. Close the registry editor and restart your PC.

Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

If this procedure resolves the issue, you are finished. If this is not the case, proceed to the next set of steps.

Step 3: Start the computer in safe mode and run system restore

  1. Click on the Start button , click the arrow next to Shut Down, 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, try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.

    • If your computer has more than one operating system, use the arrow keys to select the operating system you want to start in safe mode, and then press F8.

  3. In the Advanced Boot Options screen, use the arrow keys to select Safe Mode, and then press enter.

  4. Log your computer with a user account with administrator rights. When your computer is in safe mode, you will see marked Safe Mode in the corners of your screen.

  5. Click on the Start button , type "System Restore" in the search box, click System Restore, and then click Next. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

  6. Choose a restore point when your PC worked as expected, click Next, and then click Finish.

  7. Restart your computer normally.

Important: When you use system restore to restore the computer to a previous state, the programs and updates that you have installed after this date are deleted.

If these steps resolve the issue, you are finished. If not, try to repeat the steps and chooses an older restore point (if available). If that does not resolve the problem, contact your computer manufacturer or the technical support for further assistance.
