The circuit powering my PC has been tripping frequently, possibly because of the high temperatures and increased air-conditioner use where I live. I'm worried that repeated power interruptions could damage the computer or its components. What can I do to protect it, and what should I check to prevent the breaker from tripping so often?

For the PC itself, a properly rated UPS is the best option. It can keep the computer running briefly during an outage, giving you time to shut it down cleanly instead of losing power instantly. Choose one that can handle your computer’s power supply and monitor, with some capacity to spare.
The most important step is finding out why the breaker is tripping. If the circuit is overloaded by the PC, air conditioner, or other appliances, reduce the load or have an electrician move devices to a suitable circuit. If the breaker itself is faulty, it should be inspected and replaced by a qualified professional rather than bypassed or repeatedly reset.
A decent surge-protecting power strip is better than plugging the PC directly into the wall, but it will not solve the underlying breaker problem and may not help much with a full power cut. A UPS with built-in surge protection provides more useful protection for repeated interruptions.
