The “Diagnosing Your PC” error indicates an issue during the bootup. As a result, Windows takes matters into its own hands and starts diagnosing, which ultimately causes an endless loop. This error can occur due to corrupted system files or insufficient space.
- This endless diagnosis screen mainly appears due to insufficient space, corrupt system files, and Windows Update interruption.
- You can fix this error by running the System Restore, uninstalling the recent Windows Updates, and hard rebooting your system.
- In our experience, this “Diagnosing your PC” error can persevere for several hours, leading to lost productivity.
The error message will be displayed on the boot screen like this:

Hard Reboot
A hard reboot restarts your device by completely switching off its power. It abruptly interrupts all processes and applications running on the computer. Hard rebooting PCs and laptops can resolve many bugs and errors, including the “Diagnosing your PC” error.
A hard reboot can sometimes set your PC straight when things get jammed. We’ve tried it, and it works! And it seems others on HP Forums have had luck with it, too. Give the following method a try:
- PC Reboot: Press and hold the Power button for 15 seconds > Turn off the power outlet > Disconnect power cables and other devices > Wait for about a minute > Connect cable > Turn on the power supply > Start your PC.
- Laptop Reboot: Unplug the power cable > Disconnect all peripherals > Remove the battery > Wait for about a minute > Insert battery > Plug in the power cord > Press the power button to start your laptop.
System Restore
System Restore is a Windows utility tool designed to revert the operating system to its previously saved state. Windows named those states as restore points. This utility is beneficial when an undo is needed for the system to solve any errors or glitches.
If you’re stuck with this stubborn problem, consider rolling back with a system restore. We’ve tried it ourselves, and it’s often the quickest way to restore normality. A Microsoft Vendor at Learn Microsoft has also recommended this solution. Here are the steps:
- Open System Restore: Boot into Windows RE > Click Advanced options > Troubleshoot > Advanced options > System Restore.
- Choosing Restore Point: Click Next > Choose the latest restore point > Click Next.
- Commencing System Restore: Click on Finish.
Repair System Files
System Files can corrupt for many reasons, including viruses or malware, improper shutdown, and incomplete Windows Updates. Corrupt files can also result from a system crash or a damaged sector on your hard drive, which can cause issues like this. To repair system files, you can run the SFC and DISM Scan commands on the Command Prompt.
These commands thoroughly scan your system while repairing faulty and corrupt system files. We at Tech4Gamers have personally executed these commands, and they resolved the issue for us. Here’s how you can successfully run these commands:
- Navigate to Command Prompt: Boot your system into the Windows Recovery Environment > Click Advanced Options > Go to Troubleshoot > Advanced Options > Command Prompt.
- Access Command Prompt: Select Administrator > Provide the password if available; otherwise, leave it blank > Hit Enter.
- Running Commands: Run these commands one by one:
1. chkdsk c: /r /x 2. sfc /scannow 3. DISM /online /cleanup-image /scanhealth 4. DISM /online /cleanup-image /startcomponentcleanup 5. DISM /online /cleanup-image /restorehealth
Disable Fast Startup
The Fast Startup feature allows a computer to boot up much faster after a proper shutdown. It puts the system in hibernation mode rather than shutting it down. If the system hardware can execute fast startup, it is usually enabled by default.
However, our research found that the Fast Startup feature is known to cause several bugs and errors in the system, especially in dual-booting cases. Disabling the Fast Startup Feature helped us recover our systems, and it also helped users resolve this “Diagnosing your PC” error on Ubuntu Forums. Follow the instructions below to give this method a shot:
- Opening Command Prompt: Power your system into the Windows RE > Go to Advanced Options > Troubleshoot > Advanced Options > Click Command Prompt.
- Access Command Prompt: Select Administrator account > Enter the password if available or leave it empty > Hit Enter.
- Disabling Fast Startup: In CMD, type powercfg /h off.
Final Words
Concluding the blog, we confirm that corrupt system files are the primary cause of this error.
