What should you do if a capacitor bursts?

If a capacitor bursts, the immediate action should be to shut down the computer. A bursting capacitor can result in significant damage both to the computer's internal components and to the power supply. It may also pose a safety hazard, including the risk of fire or electric shock. By shutting down the computer as soon as possible, you minimize further damage to hardware and ensure that you are not at risk of injury from electrical components.

Continuing to use the computer could worsen the damage and lead to more severe consequences. Attempting to repair it manually without proper knowledge could also result in personal injury or voiding warranties. Contacting an internet provider is unrelated to the situation since the issue is internal to the computer. Therefore, shutting down immediately is the most prudent and safe response.
