AGP_INVALID_ACCESS

AGP aperture access violation for AGP_INVALID_ACCESS

AGP_INVALID_ACCESS is bug check code 0x00000104.

This legacy graphics/platform bug check belongs to the AGP era. It points to invalid access through the graphics aperture or address-translation path used by AGP display hardware and drivers.

How to read it in a dump

The failing driver is likely a display miniport, chipset, or AGP filter component on older systems.
AGP aperture configuration, GART mappings, and firmware/chipset settings are the key context.
Do not treat it as a modern DXGK TDR code; it is a bus/aperture mapping failure.

What to check

Check the display driver, chipset/AGP driver, BIOS AGP aperture settings, and hardware stability.
Look for memory corruption near graphics mappings.
On modern systems, confirm that the code is not from a virtualized or compatibility environment.
