If your computer suddenly runs into a black screen after disk cleanup or your Windows won’t boot with a dark screen, do you know what the reason is and how to deal with it? This post from MiniTool will introduce some effective methods to solve it, as well as a better way to safeguard your PC.

Issue: Black Screen After Disk Cleanup

When you want to free up more storage space on the drive, you might perform a disk cleanup. Generally speaking, it is a safe action that can make your computer run faster and respond more quickly. However, your PC may encounter a black screen after disk cleanup. It appears probably when critical system files or files responsible for booting Windows inadvertently get deleted during the process.

When facing a black screen, try these things first:

  • Wait and verify whether the cleanup utility is still running.
  • Check the connection between the display and your computer.
  • Disconnect all non-critical peripherals, leaving just the mouse and keyboard, and then restart the computer.

Solutions to Deal with Black Screen After Disk Cleanup

If you perform these basic troubleshooting above but they can’t work. The following methods might be useful, you can take them and try them out.

Preparation – Boot Your PC into Windows Recovery Environment

For all those solutions, it is necessary for you to boot the computer into Windows Recovery Environment (WinRE). To do that, follow the steps:

  1. Press and hold the Power button on your PC for about 10 seconds to turn it off.
  2. Then turn on the computer by pressing the Power button.
  3. Press the Power button to shut it down again as soon as the Windows logo appears.

Repeat the same process to turn off and on your PC three times. When the PC is turned on for the third time, the computer should enter into the Automatic Repair window. If not, follow the same steps until the Automatic Repair screen shows on your computer. When you see Automatic Repair couldn’t repair your PC, click Advanced options to boot into WinRE.

Fix 2: Run System File Checker

Sometimes, the corrupted system files can contribute to a black screen after disk cleanup. Thus, you can run System File Checker (SFC), a built-in tool on Windows, to repair them and fix your problem.

Step 1: Hit Troubleshoot > Advanced options > Command Prompt.

go to Command Prompt

Step 2: Input sfc /scannow in the pop-up window and press Enter to start the scan.

Step 3: It will take a while, so you need to wait patiently until the message Verification 100% complete appears.

Then restart your computer to check whether the black screen disappears.

Fix 3: Perform DISM Scan

If the SFC scan doesn’t work when your PC shows a black screen after deleting temporary files, you should try to perform the DISM scan. To do so, follow the instructions:

Step 1: Launch Command Prompt with the step above.

Step 2: Type the following commands individually and hit Enter after each:

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

run the DISM scan
Tips:
When you are running the DISM scan, it may be stuck for some reasons. Read this post to find solutions: Best Fixes: DISM /online /cleanup-image /restorehealth Is Stuck.

Fix 4: Check Disk

The logical and physical errors might be one of the reasons why there is a black screen after cleaning the PC. In this case, you should run the CHKDSK scan to check the file system of a drive for logical integrity. To do so: launch Command Prompt in WinRE, input chkdsk C: /f /r and hit Enter. You can replace C: with your target drive letter.

run CHKDSK
Tips:
If the file system of the drive is RAW, you will receive a CHKDSK is not available for RAW drives error message. Refer to this guide - [SOLVED] CHKDSK Is Not Available for RAW Drives? See Easy Fix.

Fix 5: Perform System Restore

System Restore is a tool to undo the changes to important parts of Windows with the restore point you have created. What’s more, it doesn’t delete your data or documents, so you don’t need to worry about data loss. Therefore, running System Restore is such a good choice to fix the black screen after cleaning up disk.

Step 1: Click Troubleshoot > Advanced options > System Restore after entering WinRE.

perform System Restore

Step 2: Wait for System Restore to initialize, and then click on Next.

Step 3: Choose a restore point created before the disk cleanup process and click Next.

Step 4: Finally, verify the restore details and click on Finish.

Fix 6: Reset the Computer

A factory reset is an effective method to fix all kinds of complex issues such as Windows won’t boot after disk cleanup. It is equivalent to an automatic reinstallation of Windows and you don’t have to do it manually. Here are some details to do that.

Step 1: On the WinRE screen, choose Troubleshoot > Reset this PC.

reset this PC

Step 2:  Select Keep my files or Remove everything according to your situation.

choose keep my files or remove everything
Tips:
Keep my files will only remove apps and settings but keep your personal files, while Remove everything will remove all of your apps, data, and settings. After that, you can get a new computer.

  1. Open the downloaded installation media and select Create installation media for another PC.
  2. Then create a bootable USB drive. This process will take a few minutes, please wait patiently.
