Fix Problem with Athlon Hanging AGP Programs (Windows 2000/XP)

Windows may stop responding when you use an Accelerated Graphics Port (AGP) program with an AMD Athlon processor. This is due to the memory allocated by the video adapter driver becoming corrupted.

Open your registry and find the key below.

Create a new DWORD value called "LargePageMinimum" and set it to equal "0xffffffff" (or 4294967295 in decimal).

Restart Windows for the change to take effect.

Note: This behavior is known to occur with Nvidia GeForce 256 and Matrox G400 video adapters on computers with AMD Athlon processors. This behavior is not specific to any particular video adapter type.
