parts (bulging/leaking capacitor).
2. Verify that lights are solid.
3. If shutdown is reproducible, test essential hardware configuration:
a. If no issue with hardware configuration, reinstall one non essential component at
a time to determine faulty hardware.
b. If issue persists, replace essential hardware with a confirmed working part, one at
a time. If no boot, replace system board.
Intermittent issue is difficult to reproduce and troubleshoot. It is important to record details
on shutdown frequencies, system configuration (3D video application) and operating
conditions.
