Common Causes of 0x00000012

The TRAP_CAUSE_UNKNOWN error can be triggered by several underlying issues:

Faulty hardware components, such as RAM modules or hard drives.

Step-by-Step Fixes for 0x00000012

Since this error is often hardware-related, start with the most common solutions before moving to more advanced troubleshooting. These steps are designed to be user-friendly and effective.

Check for Hardware Issues

The first step in resolving a BSOD is ensuring your hardware is functioning properly. Focus on RAM and storage devices, as these are frequent culprits:

**Test Your RAM**: Faulty or incompatible memory modules can cause system instability. Use Windows Memory Diagnostic to scan for errors:
```
Windows + R
```
Type `mdsched.exe` and press Enter.
Select “Restart now and check for problems” (recommended) or schedule a test for later.
Wait for the process to complete. If errors are found, replace your RAM modules.
**Inspect Your Hard Drive**: Run CHKDSK to check for disk corruption:
```
cmd
```
Type `chkdsk C: /f /r` (replace “C:” with the drive letter if needed) and press Enter.
Restart your computer when prompted. If errors are detected, consider replacing the hard drive.
**Monitor System Temperatures**: Overheating can lead to BSODs. Use built-in tools like Task Manager or third-party software (e.g., HWMonitor) to check CPU/GPU temperatures during normal operation. Ensure cooling fans are working properly and clean any dust buildup.

Update or Reinstall Drivers

**Use Windows Update**: Let Windows automatically search for and install the latest drivers:
```
Windows + I
```
Go to “Update & Security” > “Windows Update”.
Click “Check for updates”. If driver updates are available, install them.
**Manually Update Drivers**: For more control, update drivers manually via Device Manager:
```
devmgmt.msc
```
Expand “Disk drives” or “System devices”.
Right-click each device and select “Update driver”. Choose “Search automatically for drivers”.
Restart your computer after updating.
**Reinstall Problematic Drivers**: If a specific driver is causing the issue, uninstall it first:
```
devmgmt.msc
```
Right-click the problematic device (e.g., storage controller) and select “Uninstall device”.
Check the box for “Delete the driver software for this device” if available.
Restart your computer. Windows will reinstall the driver automatically.

Run System File Checker (SFC) and DISM

Corrupted system files can lead to BSODs. Use these built-in tools to repair them:

**System File Checker (SFC)**: Scans and repairs corrupted Windows system files:
```
cmd
```
Type `sfc /scannow` and press Enter.
Wait for the scan to complete. If issues are found, follow the on-screen instructions.
**Deployment Image Servicing and Management (DISM)**: Fixes deeper corruption in Windows components:
```
cmd
```
Type `DISM /Online /Cleanup-image /Restorehealth` and press Enter.
Wait for the process to finish. If successful, restart your computer.
**Combine SFC and DISM**: For thorough repairs, run both commands in sequence:
```
cmd
```
Type `sfc /scannow` and press Enter.
Then type `DISM /Online /Cleanup-image /Restorehealth` and press Enter.

Check for Windows Updates

Microsoft regularly releases updates that include fixes for BSOD-related bugs. Ensure your system is up to date:

Press `Windows + I` to open Settings.
Go to “Update & Security” > “Windows Update”.
Click “Check for updates”. If optional or cumulative updates are available, install them.

Disable Fast Startup (Hybrid Shutdown)

Fast startup can sometimes cause conflicts with drivers during shutdown. Disabling it may help:

Press `Windows + R`, type `control panel`, and press Enter.
Go to “Power Options” > “Choose what the power buttons do”.
Click “Change settings that are currently unavailable”.
Uncheck “Turn on fast startup (recommended)” and click “Save changes”.

Test for Third-Party Software Conflicts

If you recently installed new software, it may be conflicting with Windows. Boot into Safe Mode to check:

Restart your computer.
Hold the `Shift` key and click “Restart” from the login screen or Start menu.
Select “Troubleshoot” > “Advanced options” > “Startup Settings”.
Press `F5` to boot into Safe Mode with Networking.
Uninstall recently installed software via “Settings” > “Apps” > “Apps & features”.

Check Event Viewer for Clues

Press `Windows + X` and select “Event Viewer”.
Go to “Windows Logs” > “System”.
Look for entries with critical errors around the time of the BSOD.
