Boot into Safe Mode by forcing three restarts to trigger Automatic Repair, then navigate to Startup Settings and select Safe Mode; 2. Uninstall recent Windows Updates or suspicious software like third-party antivirus or driver updaters via Settings or Control Panel; 3. Update or roll back problematic drivers in Device Manager, focusing on display, disk, and system devices; 4.

The "Your PC ran into a problem and needs to restart" error on Windows — especially when it shows no error code — can be frustrating because it gives little direct information. However, this is typically a Blue Screen of Death (BSOD) issue caused by hardware conflicts, driver problems, corrupted system files, or faulty updates. Here’s how to fix it step by step.

1. Boot into Safe Mode

Since the system crashes on startup, the first step is to get into Safe Mode, where only essential drivers and services load.

How to enter Safe Mode:

• Force restart your PC 3 times during boot to trigger Automatic Repair.
• Once in the recovery screen:
  1. Go to Troubleshoot > Advanced Options > Startup Settings > Restart.
  2. After restart, press F4 or 4 to enable Safe Mode.

If you can get into Safe Mode, the issue is likely caused by a third-party driver, software, or update.

2. Uninstall Recent Updates or Problematic Software

If the crash started after a Windows Update or installing new software:

Remove recent updates:

• In Safe Mode, go to Settings > Update & Security > Windows Update > View update history > Uninstall updates.
• Remove any recent quality updates or driver updates.

Uninstall suspicious software:

• Go to Control Panel > Programs > Programs and Features.
• Sort by install date and remove anything recently added, especially:
  • Antivirus tools (e.g., third-party AVs)
  • Driver updaters
  • Overclocking or system optimization tools

3. Check for Driver Issues

Faulty or incompatible drivers (especially graphics, storage, or chipset) are common causes.

Steps:

• Press Win X > Device Manager.
• Look for any devices with a yellow warning icon.
• Focus on:
  • Display adapters
  • Disk drives
  • System devices (especially "Standard PCI Express Root Complex")
• Right-click each and choose Update driver > Search automatically.
• Alternatively, visit your PC manufacturer’s website (Dell, HP, Lenovo, etc.) or component maker (like NVIDIA, Intel) to download the latest compatible drivers.

Tip: If you recently updated a driver manually, roll it back by right-clicking the device > Properties > Driver > Roll Back Driver.

4. Run System File Checker (SFC) and DISM

Corrupted system files can cause silent crashes.

Run SFC:

• Open Command Prompt as Admin (via recovery menu if needed).
• Type:

  sfc /scannow

• Wait for completion. If issues are found and fixed, reboot.

Run DISM (if SFC fails):

DISM /Online /Cleanup-Image /RestoreHealth

Then run sfc /scannow again.

5. Check Disk for Errors

A failing hard drive or file system corruption can trigger restart loops.

Run in Command Prompt (Admin):

chkdsk /f /r

• It will ask to schedule the scan on next reboot — type Y and restart.

Let the scan run (can take hours on large drives). It checks and repairs bad sectors and file system errors.

6. Disable Automatic Restart on System Failure

By default, Windows hides the BSOD by restarting. Disable this to see the error code.

How:

• If you can boot normally or in Safe Mode:
  1. Press Win X > System > Advanced system settings.
  2. Under Startup and Recovery, click Settings.
  3. Uncheck "Automatically restart" under System failure.
  4. Click OK and reboot.

Now, if the crash happens again, you’ll see the actual BSOD with an error code — which makes diagnosis much easier.

7. Test Your Hardware

If software fixes don’t help, suspect hardware.

Key things to check:

• RAM: Use Windows Memory Diagnostic or MemTest86.
  • Search for "Windows Memory Diagnostic" and run it.
• Storage Drive: Use chkdsk (above) or manufacturer tools (e.g., Samsung Magician, WD Dashboard).
• Overheating: Check if fans are working; clean dust; monitor temps with tools like HWMonitor.
• Power Supply: Random crashes under load may point to PSU issues.

If you recently installed new hardware (RAM, GPU, etc.), remove it and test.

8. Reset or Reinstall Windows (Last Resort)

If nothing works, reset Windows:

• Go to Settings > Update & Security > Recovery > Reset this PC.
• Choose Keep my files (removes apps and settings, keeps personal data).
• If that fails, use a Windows installation USB to perform a clean install.

Final Notes

• This error with no code is often due to silent driver conflicts or disk corruption.
• Safe Mode is your best friend here — if you can get in, you can fix most issues.
• Always backup data when possible (use a bootable USB tool like Ubuntu Live USB if Windows won’t start).

Basically, start with software and drivers, then move to hardware. Most cases are resolved with driver rollback, SFC, or disabling updates.

It’s not complex — just methodical.
