REFERENCE_BY_POINTER BSOD fix in Windows 11 fast guide

For REFERENCE_BY_POINTER BSODs on Windows 11, start with dump evidence: if recent minidumps point to one driver, fix that first. If the dumps do not point to a clear culprit, test RAM next and then check the disk. This stop code has a value of 0x00000018. It indicates that the reference count of an object is illegal for the current state of the object.

What REFERENCE_BY_POINTER means on Windows 11

REFERENCE_BY_POINTER is bug check 0x00000018. It is caused by an inconsistency in an object’s reference count. Typically, that happens when a driver decreases the reference count too many times, when the count reaches zero while handles are still open, or when the count drops below zero. The same stop code can also appear on Windows 10 and Windows 11.

When this appears once after a new driver or app install, treat it as a clue. When it repeats across different boots, the crash is usually tied to the same underlying reference-count problem.

Likely causes, ranked from most common to least obvious

• Bad or mismatched drivers. This is the first thing to check, especially after a recent update.
• Driver reference-count bugs. The driver may be dereferencing an object too many times or in the wrong order.
• Problematic third-party software that installs drivers. Storage, virtual drive, security, or VPN software can install filter drivers that affect object handling.

How do I tell whether this is a driver, RAM, or storage problem?

The quickest way to sort it out is to compare the crash pattern with the last change, then use the minidump and one controlled test at a time. A single crash after one driver change points one way; a boot loop with no recent changes points another, and the next step should fit that pattern.

What repeated crashes at startup usually mean

Boot-loop behavior usually means a startup driver, filter, or system-level app is loading before the desktop appears. Safe Mode is a useful first cutoff point because it loads fewer drivers and services. If Safe Mode is stable, the fault is usually in a startup driver or service.

What a one-time crash after installing software usually means

A one-off crash after installing a VPN, backup tool, or virtual disk app usually points to a conflict in the driver layer. Uninstall the new app first, then restart. If the machine stays stable, that install was the trigger.

How to use the result to choose the next step

If the crash vanishes after one removal, keep the machine on the stable version and avoid reinstalling the same build. If it persists, move to the next layer in the table instead of repeating the same fix. That order saves time and cuts false leads.

1. Note the last change before the first crash.
2. Check whether Windows reaches the sign-in screen or loops before it.
3. Match the symptom to the table.
4. Run the first test for that layer only.
5. Proceed to the next layer if the crash remains.

Start with RAM checks before driver deep dives

Windows Memory Diagnostic is often a good first test when the cause is unclear, because bad RAM can corrupt driver data and make a healthy driver look guilty. If memory is healthy, you have better reason to spend time on drivers or the disk.

1. Press Win + R, type mdsched.exe, and press Enter.
2. Select Restart now and check for problems.
3. Let the test finish after the reboot.
4. Check the result in Event Viewer > Windows Logs > System if Windows does not show it directly.
5. If errors appear, test each memory module separately or replace the failing stick.

If memory testing reports faults, stop chasing drivers first. Replace the bad module or run vendor diagnostics before any deeper software work.

Should I run CHKDSK or Memory Diagnostics first for this error?

Run Memory Diagnostic first when you do not yet know the source. Memory problems can corrupt the file system, so CHKDSK can show damage without telling you what caused it. Once RAM looks healthy, CHKDSK is the next sensible check for disk errors.

1. Open Windows Memory Diagnostic and test RAM first.
2. If RAM passes, open Command Prompt (Admin).
3. Run chkdsk C: /f and allow the scheduled reboot if prompted.
4. If Windows still crashes, review the dump and the disk health result together.
5. If CHKDSK reports repeated errors, back up data and inspect the drive.

A clean CHKDSK result does not clear the disk forever; it only removes one likely layer. If crashes continue, the next target is usually a driver.

How do I isolate a bad driver or app?

Use Safe Mode to reduce loaded drivers, then Clean Boot to separate Microsoft services from third-party startup software. If the system stays stable there, uninstall the newest app first. Graphics drivers are common suspects, and Windows can reinstall one automatically after a restart.

1. Boot to Safe Mode: Settings > System > Recovery > Advanced startup > Restart now > Troubleshoot > Advanced options > Startup Settings.
2. If Safe Mode works, open msconfig, choose a Clean Boot, and restart.
3. Uninstall recent software one item at a time, especially VPN, backup, encryption, and virtual drive tools.
4. Open Device Manager and roll back or uninstall the Graphics Card driver if the crash began after a display update.
5. Use Device Manager > (device) > Properties > Driver tab > Roll Back Driver / Uninstall device.
6. Restart and let Windows reinstall the graphics driver if needed.
7. Use Driver Verifier Manager only after creating a system restore point.

Reported conflicting apps include TrueCrypt, VeraCrypt, and Daemon Tools. Those do not mean every install is bad; the issue is that some versions can install filter drivers that affect reference counts.

Safe Mode entry:
Settings > System > Recovery > Advanced startup > Restart now > Troubleshoot > Advanced options > Startup Settings

Driver rollback path:
Device Manager > (device) > Properties > Driver tab > Roll Back Driver / Uninstall device

Memory test:
Windows Memory Diagnostic (mdsched.exe)

System File Checker + DISM:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

How do I use Driver Verifier without making the crash worse?

Create a restore point first. Then open an elevated Command Prompt and enable Driver Verifier for non-Microsoft drivers only with verifier /standard /driver <drivername>.sys or verifier /standard /all if you need to narrow a broad driver issue. Reboot and test. To turn it off, boot Safe Mode if needed and run verifier /reset, then restart.

How to read crash dumps with WinDbg

WinDbg is the shortest path from guesswork to evidence when minidumps exist. Open the dump, run the analysis command, and look for the faulting module name. That module can point to a driver or a filter driver instead of a random victim.

1. Collect the dump from C:\Windows\Minidump\*.dmp.
2. Open it in WinDbg.
3. Run !analyze -v.
4. Check the MODULE_NAME, IMAGE_NAME, and stack for a repeated third-party driver.
5. Run !object when the analysis points to object lifetime issues.
6. If the same driver appears across multiple dumps, remove or update that driver first.

If the dump shows memory corruption without a stable module, treat that as a RAM or driver lead, not proof of a bad app.

Still not working?

If the crash survives RAM checks, CHKDSK, Safe Mode, Clean Boot, and driver rollback, move to a restore point or repair install before replacing hardware. At that stage, the crash may be a symptom of deeper instability rather than the root cause.

How do I fix REFERENCE_BY_POINTER BSOD in Windows 11?

Start with the latest minidump, then test RAM with mdsched.exe, run chkdsk C: /f if memory passes, and isolate startup software with a Clean Boot. If a recent driver is involved, roll it back in Device Manager. If the crash loop blocks normal use, boot Safe Mode first.

What does the REFERENCE_BY_POINTER stop code mean?

It points to an object reference-count problem. The next step is to identify whether the dump names a driver or filter driver, then act on that result.

Can bad RAM cause REFERENCE_BY_POINTER blue screens?

Yes. Bad RAM can corrupt driver data and object counts, which can make the stop look like a software problem. Run Windows Memory Diagnostic first, then retest with individual sticks if the tool reports an error or if crashes keep returning.

Should I run CHKDSK or Memory Diagnostics first for this error?

Run Memory Diagnostic first when the cause is unclear, then use chkdsk if RAM passes. That order avoids chasing disk damage that may have been created by memory corruption. If both pass, the next step is minidump analysis in WinDbg or a driver rollback.

Which third-party apps are known to trigger REFERENCE_BY_POINTER BSODs?

Reported conflicts include TrueCrypt, VeraCrypt, and Daemon Tools. Uninstall the newest version first, then reboot and test before reinstalling anything else.

Do I need to reinstall my graphics driver for this stop code?

If the crash began after a display update or during gaming, yes, that is a reasonable next step. Use Device Manager to roll back or uninstall the graphics driver, then restart so Windows can load a fresh copy. If the issue remains, do not keep repeating that step.

Prevention: after the system is stable, avoid stacking multiple driver updates and filter apps on the same day. Change one thing, then test. That makes the next crash far easier to trace.
