Your Microsoft Windows 2000-based computer stops responding after the computer runs without interruption for more than one year. If your computer uses a hardware abstraction layer (HAL) that is included with Windows 2000, your computer may stop responding after 497 days. If your computer uses a third-party custom HAL, your computer may stop responding after a longer time.
This problem occurs because the NtGetTickCount function returns a large gap when the KeTickCount function wraps from an address of 0xffffffff to an address of 0x00000001 0x00000000. The tick count produces a large gap because of 64-bit to 32-bit conversions.
