Fix AGP_GART_CORRUPTION Error in Windows 11
So, what causes this issue to raise its head? To me, it typically stems from problems with AGP (Accelerated Graphics Port) drivers, outdated graphics hardware, or memory corruption. More often than not, you can get the better of it by just eliminating these culprits.
1. Update Your Graphics Driver
Note that the outdated or buggy GPU drivers have long been the common cause of this error. Keeping them updated helps not only facilitate compatibility with Windows 11 but also allow them to go about their business with the needed smoothness.

- Expand the Display adapters section with the help of the tiny downward arrow.
- Then, right-click your GPU and choose Update driver in the menu.
- Up next, select Search automatically for drivers and go ahead to update them.
2. Uninstall and Reinstall Graphics Driver
Corrupted driver files can cause the BSOD. A clean reinstall removes all broken dependencies.
- Go to Device Manager on your PC > right-click your graphics card and choose Uninstall device.
- After that, be sure to restart your PC to automatically reinstall the latest graphics driver.
3. Run Memory Diagnostic Tool
Be warned that the faulty RAM can lead to data corruption that causes this error on your PC. Hence, I’d suggest you run the memory diagnostic tool to nab and fix the conflicting element.
