Ensure the power cable is securely connected and the power outlet is functional. Check if the power button is responsive. If the issue persists, try using a different power cable or contact Sony support for further assistance.

The Sony PCV-RZ55G supports standard 3.5-inch IDE hard drives. Ensure any new hard drive is compatible with these specifications for successful installation.
Ensure the computer is placed in a well-ventilated area. Clean dust from the vents and internal components using compressed air. Consider adding additional cooling fans or replacing the thermal paste on the CPU.
While the PCV-RZ55G has an AGP slot for graphics cards, compatibility with modern cards may be limited. Check the power supply and space within the case for any new card, and consult the card's manufacturer for compatibility information.
