Won't boot
Start with the clock capacitor. A leaking clock capacitor is one of the most common reasons an aging Xbox stops booting. Before deeper diagnosis, open the console and inspect that area for corrosion.
Narrowing the cause
A console that will not boot can fail at power, storage, drive, or board level. Work from simplest to hardest so you do not chase the wrong fault.
- Confirm power. Check the outlet, cable, and power supply. Listen for the fan and watch for any front-panel light at all.
- Read the light and any error. A solid green light with no video, a flashing light, or an on-screen Frag error each points in a different direction. Note exactly what you see.
- Inspect the board. Look for clock capacitor leakage, corroded traces, and bulged capacitors. Clean and repair as needed.
- Test storage and drive. A locked, missing, or failed hard drive, or a dead DVD drive, can halt boot. Reseat IDE and power cables.
Next steps
If you get an on-screen error number, consult the Boot and Frag error code page. If the light flashes a color pattern, see the Flashing light page. For a console that boots but then loops, see the Softmod failed page. troubleshooting
