A burning smell on a desktop computer is a serious issue that indicates a hardware malfunction or failure. It can be caused by overheating, a faulty power supply, a malfunctioning motherboard, or a short circuit12. If left unchecked, it can damage the components, cause a fire, or harm the user.
The first thing the technician should do when troubleshooting a burning smell on a desktop computer is to unplug the computer from the power source. This will stop the flow of electricity and prevent further damage or fire. The technician should also wear protective gloves and eye wear to avoid contact with any hot or hazardous parts.
The other options are less likely to be the first step in troubleshooting, because:
*Locating a fire extinguisher is a good precaution, but it should not be done before unplugging the computer.
The fire extinguisher should only be used if there is visible smoke or flames coming from the computer, and only after unplugging it and ensuring that it is safe to do so.
*Calling the fire department is an extreme measure that should only be done if there is an actual fire that cannot be controlled by the fire extinguisher. It should not be done before unplugging the computer and trying to identify and fix the problem.
*Removing the desktop cover is a necessary step to inspect the internal components and find the source of the burning smell. However, it should not be done before unplugging the computer, as it can expose the technician to live wires and electric shocks.
