This error typically occurs when the kernel attempts to switch from user mode to kernel mode, often due to driver or hardware issues. If you’re experiencing this BSOD, don’t worrythis guide will walk you through identifying and fixing the problem step by step.

What Causes the PANIC STACK SWITCH (0x0000002B) Error?

The 0x0000002B error is usually triggered by:

Corrupt or outdated drivers, especially those related to hardware components like graphics cards, network adapters, or storage controllers.
Faulty RAM or hardware issues, including faulty memory modules or overheating.
Malware or system file corruption affecting critical Windows components.
Incompatible software or drivers installed on your system.
Overclocking or BIOS/UEFI misconfigurations
, which can destabilize hardware interactions.

How to Fix PANIC STACK SWITCH (0x0000002B) BSOD

Method 1: Run System File Checker and DISM

Corrupted system files can trigger this error. Use Windows’ built-in tools to repair them:

Press Win + X, then select Terminal (Admin) or Command Prompt (Admin).
In the command prompt, run these commands one by one and wait for each to complete:
```
DISM /Online /Cleanup-Image /RestoreHealth
```
```
sfc /scannow
```

Restart your PC after running both commands.

Method 2: Update or Reinstall Drivers

Outdated or faulty drivers are a common cause. Follow these steps:

Press Win + X, then select Device Manager.
Look for devices with a yellow exclamation mark (problematic hardware) and right-click to update or uninstall them.
If no issues are flagged, manually check drivers for:
- Graphics card (NVIDIA/AMD/Intel)
- Network adapter
- Chipset drivers
Download the latest versions from the manufacturer’s website.

Method 3: Check for RAM and Hardware Issues

Faulty RAM or overheating can cause this error. Test your hardware:

Run Windows Memory Diagnostic:
- Search for Windows Memory Diagnostics in the Start menu, then run the tool.
- Follow on-screen instructions to check for errors.
Check for overheating:
- Use third-party tools like HWMonitor or HWiNFO to monitor temperatures.
- Ensure fans are working and clean dust from vents if needed.

Method 4: Run CHKDSK for Disk Errors

Corrupted disk sectors can trigger BSODs. Run CHKDSK to scan your drives:

Open Command Prompt as admin.
Type the following command (replace C: with your drive letter if needed):
```
chkdsk C: /f /r
```
Press Y to confirm, then restart your PC when prompted.

Method 5: Check for Malware and System Cleanup

Malware or junk files can corrupt system processes. Scan your PC:

Run a full scan with Windows Defender (Settings > Update & Security > Windows Security).
Use third-party tools like Malwarebytes for deeper scans.
Free up disk space by deleting temporary files via Settings > System > Storage > Free Up Space.

Method 6: Test in Safe Mode

If the error persists, boot into Safe Mode to check if a third-party driver is causing it:

Restart your PC and hold Shift + F8 (or repeatedly press F8 for older Windows versions).
Select Safe Mode with Networking.
If the system is stable, disable recently installed software or drivers one by one to identify the culprit.

Method 7: Check BIOS/UEFI Settings (Advanced)

If you’ve overclocked your CPU/GPU or have custom BIOS settings, reset them:

Restart and enter BIOS/UEFI (usually by pressing Del, F2, or F12 during boot).
Reset to default settings or disable overclocking features.
Save changes and exit.
