Fix Graphics No More Elements in Dataset (0x0026234C)

Yeah, this one gets annoying fast. You're either trying to install a new Nvidia or AMD driver, or you launch a game, and bam — error 0x0026234C. The display driver crashes, maybe the screen flickers. Don't panic. It's a driver corruption issue, and I've got a fix that works.

The Real Fix: Clean Driver Removal with DDU

Skip Windows' built-in uninstaller. It leaves junk behind. The only reliable way is Display Driver Uninstaller (DDU). Here's the exact process I use — done it a hundred times.

1. Download DDU from the official site (guru3d.com). Get the latest version.
2. Boot into Safe Mode. Press Windows key + R, type msconfig, go to Boot tab, check Safe boot (Minimal), restart. Or hold Shift while clicking Restart in the Start menu, then Troubleshoot > Advanced options > Startup Settings > Restart > press 4.
3. Run DDU in Safe Mode. Select your GPU manufacturer (Nvidia or AMD) from the dropdown on the right. Click Clean and restart.
4. Your PC will reboot normally. Windows will install a basic driver. That's fine.
5. Download the latest driver from Nvidia or AMD's site. For Nvidia, grab the Game Ready driver. For AMD, the Adrenalin edition.
6. Install the driver with a clean install option (Nvidia: check "Perform a clean installation"; AMD: check "Factory Reset").
7. Restart one more time.

Had a client last month whose entire print queue died because of this — not the same error, but same root cause: corrupted driver stack. This process fixed both.

Why This Worked

Error 0x0026234C means "no more elements in dataset" — the graphics driver's internal data structure got corrupted. Usually happens when you install a new driver over an old one, or Windows Update pushed a bad driver, or a game's DirectX call hit a broken pointer. DDU wipes out every trace: registry keys, driver files, service entries. You start fresh. No leftovers to trip over.

Less Common Variations

If DDU didn't fix it, here's two other things I've seen cause the same error:

1. DirectX Runtime Corruption

Sometimes the DirectX files themselves get hosed. Run the DirectX End-User Runtime Web Installer from Microsoft. It'll repair missing or damaged .dll files. Also run sfc /scannow in an admin command prompt — that checks system files.

2. Overclocking Instability

If you've overclocked your GPU or RAM, dial it back to stock. I've seen this error on a Ryzen 5600X with unstable memory timings. The GPU driver tried to allocate a buffer that didn't exist. Reset your BIOS to defaults, then test. If stable, slowly reapply your overclock.

Prevention: Keep Your Drivers Clean

Don't install driver updates over old ones. Always use DDU at least once a year, or whenever you switch GPU brands. Also, disable automatic driver updates in Windows: go to System Properties > Hardware > Device Installation Settings > No. Windows Update loves to overwrite your stable driver with a generic one — and that's how corruption starts.

One last thing: if you're on a laptop with switchable graphics (Intel + Nvidia/AMD), make sure the dedicated GPU driver is from the laptop manufacturer's site. Generic drivers from Nvidia or AMD can cause this error on some models. I've seen it on Dell XPS 15s and Lenovo Legions.
