Even if you can still boot your computer, you need lớn apply some troubleshooting steps to prsự kiện such an error from happening again. But you are the lucky ones that can fix the error much more easily with a bootable computer.

Method 1. Boot into Safe Mode và then Boot Normally

Safe Mode is a diagnostic mode of Windows. It starts your PC with the minimal necessary programs & services. In Safe Mode, you can fix some system-related problems by uninstalling incompatible software/driver, deleting problematic files, removing viruses, and more. Even if you vì nothing, booting into Safe Mode is useful to lớn repair some system errors by helping the storage system to lớn be reaccessed.

On a functional computer, you can enter Safe Mode via Settings:

The Windows operating system and some applications installed need sufficient free space lớn function properly. If your system drive sầu, generally a C drive sầu, is almost out of space, you should consider extending the system partition to lớn create more space for your OS.

Method 4. Chechồng System Log in Event Viewer

Checking the system log in Event viewer is helpful khổng lồ find the culprit of the "Your PC ran inkhổng lồ a system" error in Windows 11/10/8/8.1, especially for a problematic device or driver.

Situation 2. You Can"t Boot Windows and See "Your PC did not start correctly"

In some cases, your PC will restart & prepare a startup repair automatically after the error message appears, resulting in the "Your PC did not start correctly" screen. Here you can see two options: Restart và Advanced options.


If you cliông xã "Restart", it"s almost inevitable the computer will come with the same error screen. Thus, you should choose "Advanced options" instead. Afterwards, continue khổng lồ choose "Troubleshoot" > "Advanced options".

Here you will see five sầu or six options, depending on your Windows version, including System Restore, System Image Recovery, Commvà Prompt, Startup Settings, and Go back to the previous build. Here is a brief explanation:

If you have created a restore point, then using the System Restore feature will bring your computer baông xã to lớn a functional state. If not, this option is useless.Similarly, if you have created a system image, you can perform a System Image Recovery khổng lồ bring your system baông xã to life. If not, it"s just not the option for you.In this case, the computer had tried a Startup Repair and failed. Therefore, it"s unnecessary to lớn try it again.In Comm& Prompt, you can use comm& lines khổng lồ exedễ thương operations.In Startup Settings, you can enter Safe Mode, disable automatic restart after failure, & more.The "Go baông xã khổng lồ the previous build" will bring your computer baông chồng to an earlier version.Method 1. Perform System Restore

If you have sầu a system restore point available, you can persize a system restore:

Step 1. In the Windows Boot Options thực đơn, select "Troubleshoot" > "Advanced Options" > "System Restore".

Step 2. Choose a previous working state (data) lớn restore your computer.

Step 3. Wait until Windows restores your system. Then restart the computer.


Method 2. Persize System Image Recovery

Alternatively, you can perform a system image recovery if you have created a system image before the issue arise.

Step 1. Connect the external hard drive that contains the system image khổng lồ your computer.

Step 2. In the Windows Boot Options menu, select "Troubleshoot" > "Advanced Options" > "System Image Recovery".

Step 3. Choose the system image you want lớn recover.

Step 4. In the Re-image your computer wizard, select the system image, and clichồng "Next".

Step 5. Follow the wizard khổng lồ format the disks & restore the system.

Step 6. Restart your computer.


Method 3. Restore Registry Configuration

Don"t have any restore point or system image? No worry. Based on the details above, here I recommend you select "Comm& Prompt" lớn restore the registry.

The registry is a database that contains the configuration data for the Windows operating system và most of the applications. That is why changes in the registry may influence the functionality of your computer or programs. Registry files may get deleted accidentally by yourself or by some program. And that could result in serious problems just lượt thích "Your PC ran into a problem và needs lớn restart". Luckily, the changes can be reverted with the registry backup files, which you can complete via Comm& Prompt.

Step 1. Choose "Comm& Prompt" among mỏi the options.

Step 2. Select the account và enter the password.

Step 3. In Comm& Prompt, enter the following command in order:

C:CD WindowsSystem32CD configDIRCD regbackDIR CD..REN mặc định default1ren sam sam1ren security security1ren software software1ren system khổng lồ system1CD regbackcopy * c:windowssystem32config

Step 4. Type exit. In the "Choose an option" screen, choose "Turn off your PC" và then start your computer.

Simply speaking, the commands above sầu serve sầu the purpose of replacing the existing system32 config files, which might have been changed incorrectly, with the ones in the backup thư mục. This method will certainly work if the "Your PC ran inlớn a problem" error is caused by registry changes.

If restoring the registry comes in vain, you can choose "Startup Settings" và enter Safe Mode to try more solutions.

Situation 3. You Are Stuck in the "Your PC ran into a problem" Loop

Unlượt thích either of the two cases above sầu, you have no options available to choose from. All you have sầu is the repeated restart và error circle. In a situation lượt thích this, you can either recover data from the corrupted OS or fix the problem with the Windows installation CD/DVD. If you don"t have an installation disc, you can create a Windows installation truyền thông as a substitute. With the Windows installation truyền thông, you can repair your computer via the Advanced options which you have sầu no access khổng lồ currently.

Preparation: Steps to lớn access the Advanced options via the Windows installation media:

Step 1. Create a Windows installation media according to the official guide supplied by Microsoft.

Step 2. Connect the bootable truyền thông to lớn your computer & boot your computer from the device.

Step 3. Wait for the installation files to load.

Step 4. In the Windows Setup window, choose "Next".

Step 5. Clichồng "Repair your computer" in the Setup window and choose "Troubleshoot" > "Advanced options".

In situation 2, I have sầu explained what these Advanced options can do. To fix the "Your PC ran into lớn a problem & needs to lớn restart" in Windows 10/11, you can apply the following solutions in order.

Method 1. Perform Startup Repair

Method 2. Perform System Recovery/System Image Recovery

The precondition lớn use such options is that you have sầu a restore point or system image available. If not, switch to lớn other workable ways.

Method 3. Restore the Registry in Commvà Prompt

Did you change the registry on your computer recently? If you did, enter Comm& Prompt & follow the steps detailed in situation 2 khổng lồ bring the registry lớn an earlier working state.

Method 4. Enter Safe Mode

Uninstall incompatible softwareUpdate driverRemove virus/malwareRun System File Checker tool

To uninstall problematic software:

Step 2. Cliông chồng the target software and cliông chồng "Uninstall".


To update the hard drive/motherboard driver: Since your computer cannot boot properly, you need to update the hard drive sầu driver or motherboard with a CD or USB that contains the driver. You can download the driver from the manufacturer"s website.
