If you see a Windows 10 stop code that mentions a “reference by pointer,” it usually means a driver or system service tried to use a memory address that has already been freed or is invalid. The fix is to update or remove the faulty driver, run memory diagnostics, and repair system files; in many cases, booting into Safe Mode and using System Restore resolves it quickly.
What Does “Reference by Pointer” Mean in a Stop Code?
Windows stop codes (also called bug checks or BSOD errors) are hexadecimal codes that tell you why the system crashed. The phrase “reference by pointer” is not a standalone error code; it usually appears in the descriptive text of a bug check such as IRQL_NOT_LESS_OR_EQUAL (0x0000000A) or SYSTEM_SERVICE_EXCEPTION (0x0000003B). The kernel uses pointers to access memory objects; when a driver passes a bad pointer—one that points to freed or paged-out memory—the system cannot safely continue and stops.
Common triggers include outdated graphics drivers, faulty storage drivers, corrupted system files, or failing RAM. The error can also appear after a Windows update that introduced an incompatible driver.
How to Read the Stop Code and Identify the Culprit
When the BSOD appears, the screen shows the stop code and sometimes the name of the driver or file that caused it. Write down the full code (e.g., 0x0000000A) and any file name like nvlddmkm.sys or ntfs.sys. That file name is your first clue—it tells you which driver to update or remove.
If the screen disappears too quickly, disable automatic restart:
- Boot into Safe Mode (see below).
- Open Control Panel > System > Advanced system settings.
- Under Startup and Recovery, click Settings.
- Uncheck Automatically restart.
- Click OK and reboot normally. The next crash will stay on screen.
You can also view crash details in Event Viewer under Windows Logs > System, filtering by source “BugCheck.”
Step-by-Step Fixes (In Order of Likelihood)
Try these in order; each one addresses a common cause.
1. Boot into Safe Mode
Safe Mode loads only essential drivers, so if the system starts there, the problem is a third-party driver. To enter Safe Mode:
- Restart your PC. When the sign-in screen appears, hold Shift and click Power > Restart.
- Select Troubleshoot > Advanced options > Startup Settings > Restart.
- Press 4 or 5 to boot into Safe Mode (with or without networking).
Once in Safe Mode, proceed to the next steps.
2. Update or Roll Back the Suspect Driver
If you identified a driver file from the BSOD, update it:
- Open Device Manager (right-click the Start button).
- Find the device (e.g., Display adapters, Network adapters).
- Right-click and choose Update driver > Search automatically.
- If an update is not found, go to the manufacturer’s website and download the latest driver manually.
If the issue started after a recent driver update, roll back instead: in Device Manager, right-click the device, choose Properties > Driver > Roll Back Driver.
3. Run System File Checker and DISM
Corrupted system files can cause pointer errors. Open Command Prompt as administrator and run:
sfc /scannow
After that finishes, run:
DISM /Online /Cleanup-Image /RestoreHealth
Restart and check if the error persists.
4. Test Your RAM
Faulty RAM is a frequent cause of pointer-related crashes. Use the built-in Windows Memory Diagnostic:
- Press Win + R, type
mdsched.exe, and press Enter. - Choose Restart now and check for problems.
- The system will run a memory test and restart. After restart, open Event Viewer and look for results under MemoryDiagnostics-Results.
If errors are found, replace the faulty RAM module. You can also test with Memtest86 (free, bootable) for a more thorough check.
5. Use System Restore
If the crashes started recently, restore your system to an earlier point:
- In Safe Mode, type
rstrui.exein the Start menu and press Enter. - Choose a restore point before the first crash.
- Follow the prompts and restart.
6. Check for Windows Updates and Driver Updates
Go to Settings > Update & Security > Windows Update and install all pending updates. Also check Optional updates for driver updates. Sometimes Microsoft ships a fix for a known bug check.
7. Disable Fast Startup
Fast Startup can cause driver issues after shutdown. Disable it:
- Open Control Panel > Power Options.
- Click Choose what the power buttons do.
- Click Change settings that are currently unavailable.
- Uncheck Turn on fast startup.
- Save changes and restart.
Common Misconceptions and Pitfalls
Many users think a “reference by pointer” error means a hardware failure, but in most cases it is a software/driver conflict. Do not immediately buy new RAM or a new hard drive—try the software fixes first.
Another mistake is skipping the DISM step after running SFC. SFC only repairs corrupted files if the component store is healthy; DISM fixes the store itself. Run both in order.
Also, be cautious with third-party “driver updater” tools—they often install outdated or incompatible drivers. Stick to Windows Update or the manufacturer’s site.
When to Consider a Clean Install
If none of the above works, a clean installation of Windows 10 is the most reliable solution. Back up your data first, then use the Reset this PC feature (Settings > Update & Security > Recovery) or create a bootable USB with the Media Creation Tool. This eliminates any lingering driver or registry corruption.
Frequently Asked Questions
What is the exact stop code for “reference by pointer”?
There is no single code; the phrase appears in the description of several bug checks. The most common are IRQL_NOT_LESS_OR_EQUAL (0x0000000A) and SYSTEM_SERVICE_EXCEPTION (0x0000003B). Look for the actual hexadecimal code on the BSOD to narrow down the cause.
Can a faulty GPU cause this error?
Yes, a failing graphics card or its driver is a common trigger. Update the GPU driver first; if the error persists, test with a different GPU if possible.
Will reinstalling Windows fix it?
Usually yes, because a clean install removes all third-party drivers and corrupted system files. However, if the error is due to failing RAM or a dying hard drive, the hardware issue will remain.
How do I find the driver that caused the crash?
Check the BSOD screen for a file name like xxx.sys. Alternatively, use the BlueScreenView utility (free) to analyze minidump files in C:\Windows\Minidump.
Is it safe to keep using the PC after a pointer error?
It is safe to boot and try fixes, but if the error occurs repeatedly, continued use may lead to data loss. Back up important files before attempting extensive troubleshooting.
