reported hard resets when Fable plays its in‑game movies after fitting a VisionTek Radeon X1550 AGP card. was onto a common suspect — driver/compatibility problems — but the installer saying "not compatible" while the card is listed in Microsoft’s HCL points toward an OS/driver mismatch or a need for an AGP/legacy driver package rather than a simple driver update.

Recommended diagnostic checklist:

  • Disable automatic restart on system failure (Windows: System Properties > Advanced > Startup and Recovery) to capture a stop code and offending module.
  • Inspect Event Viewer/System logs and any minidump for names like ATI driver files (this narrows causes).
  • Remove the current display driver completely and boot with the basic display driver to see whether movies still force a reset.
  • Use the VisionTek-supplied AGP driver or the AMD/ATI legacy branch that matches the exact Windows version; generic installers sometimes drop AGP support. Try Windows compatibility mode if installers complain.
  • Rule out power/thermal faults: monitor GPU temps, verify fan/heatsink seating, and test with a known-good PSU or the card in another machine.
  • In BIOS, try disabling AGP fast write or forcing a lower AGP rate; avoid changing AGP voltage unless board documentation explicitly permits it.

If a kernel module tied to ATI appears in a crash dump, that confirms driver-side troubleshooting; otherwise failing hardware (card or PSU) becomes more likely. VisionTek legacy-driver resources and the card's support notes for AGP-era systems are appropriate next references.
