What is a typical sign that a capacitor is bad or has failed on a computer?

A typical sign that a capacitor is bad or has failed in a computer is visible physical damage, such as bulging, leaking, or corrosion on the capacitor itself. Additionally, symptoms like system instability, random shutdowns, failure to power on, or unusual noises can indicate capacitor issues. If the computer experiences frequent crashes or the motherboard fails to function properly, it may also point to faulty capacitors.
