Explanation:

Upgrading a power supply to add a GPU typically requires more wattage to accommodate the additional power demands. Although the current power supply is 380W, adding a GPU with a six-pin power connector suggests a mid-range graphics card, which would likely need a total system power supply in the range of
450W to ensure adequate power for all components, providing a good balance between capacity and safety margins.

A clicking hard drive is usually a sign of a mechanical failure, where the read/write heads are not functioning properly or the platters are scratched or broken. This can be caused by physical shock, such as dropping the laptop while it was turned on. A damaged hard drive may not be able to boot up the operating system or access the data stored on it. This is a serious problem that requires data recovery and hard drive replacement.
