Fixed: ERROR_BUFFER_ALL_ZEROS (0x000002F2) in Windows

What actually causes 0x000002F2

I've seen this error pop up in two main places: during driver installations and after a sudden power loss or blue screen. The system expects to read data from a memory buffer, but finds only zeroes instead. That’s the kernel saying “I asked for something, you gave me nothing, that’s not valid.”

This isn't a hardware failure in my experience. It's almost always software — a driver package that got corrupted mid-write, a leftover dump file that didn't complete, or the driver store itself got scrambled. We'll walk through each fix from most common to least.

Cause #1: Corrupt driver package from a partial install

This is the one I see the most. You're installing a new piece of hardware — a graphics card, a network adapter, maybe a printer — and the installer crashes partway through. Next boot, you get 0x000002F2. The driver files wrote to disk, but the buffer that holds the version info or checksum never got filled. It's all zeroes.

Here's the fix:

1. Boot into Safe Mode. Hold Shift while clicking Restart, then go to Troubleshoot > Advanced options > Startup Settings > Restart. Hit 4 for Safe Mode.
2. Once in Safe Mode, open Device Manager. Right-click the Start button and pick Device Manager.
3. Look for any device with a yellow exclamation mark — that's your troublemaker. But even if you don't see one, expand categories like Network adapters, Display adapters, and Universal Serial Bus controllers.
4. Right-click the device that gave you the error and choose Uninstall device. Check the box that says “Delete the driver software for this device.”
5. After uninstalling, reboot normally. Windows will try to reinstall the driver fresh. If you're smart, download the driver package from the manufacturer's site first — not Windows Update — and run the installer again from scratch.

Expected outcome: After reboot you shouldn't see 0x000002F2. If you do, move on to cause #2.

Cause #2: Leftover memory dump files from a prior crash

Here's a subtle one. Windows writes crash dumps when it blue-screens. If the crash happens during the dump writing phase — power loss, manual reset — the dump file can be all zeroes. Then on next boot, the system reads that zeroed file and throws 0x000002F2 because it expects actual data.

How to clean out the junk:

1. Press Win + R, type %SystemRoot%\Minidump and press Enter.
2. If that folder exists, delete everything inside. If it doesn't exist, skip to step 4.
3. Also check %SystemRoot%\MEMORY.DMP — this is the full dump file. Delete it if it's there. It's usually huge (several GB).
4. Now open Disk Cleanup: hit Win + S, type “Disk Cleanup”, pick the drive Windows is on (usually C:).
5. Click “Clean up system files.” Check “System error memory dump files” and “System error minidump files.” Click OK, confirm deletion.

Expected outcome: After cleanup, restart. If the error was from a broken dump, it's gone now. If it persists, it's probably the driver store itself.

Cause #3: Corrupt driver store (Windows 10/11)

This one's rarer but nasty. The driver store — C:\Windows\System32\DriverStore\FileRepository — holds cached driver packages. If a package got partially written, it can cause 0x000002F2 on boot when the system tries to load that driver's metadata. You'll see this most often after a Windows Update that failed halfway, or after using a third-party driver cleaner that deleted files it shouldn't have.

Fix — use DISM to restore the store:

1. Open Command Prompt as administrator. Hit Win + S, type “cmd”, right-click, choose Run as administrator.
2. Run this command: DISM /Online /Cleanup-Image /RestoreHealth
3. Wait for it to finish. It might take 10-20 minutes. Don't interrupt it.
4. After it completes, run sfc /scannow to check system files.
5. Restart your PC.

If DISM can't fix it — that happens — you'll need an in-place repair install. That's a full Windows reinstall that keeps your files. Download the Windows 10 or 11 Media Creation Tool, run it, and choose “Upgrade this PC now.” It reinstalls Windows while preserving your apps and data. This will rebuild the entire driver store.

Quick-reference summary table

If none of these work, you're likely looking at a corrupted Windows installation. Back up your data and do a clean install. That always wipes 0x000002F2 — because you're starting fresh with no zeroed buffers anywhere.
