List five simple things to consider when attempting to solve a PC problem?
1. If you smell any burnt parts or odors, don't try to turn the system on. Identify the component that is fried and replace it. 2. Is the power cord plugged in? If it is plugged into a power strip or surge suppressor, is the device turned on and also plugged in? 3. Is the power outlet controlled by a wall switch? If so, is the switch turned on? 4. Are any cable connections loose? 5. Is the circuit breaker blown? Is the house circuit overloaded? 6. Are all switches on the system turned on? Computer? Monitor? Uninterruptible power supply? 7. When you first plug up power to a system and hear a whine coming from the power supply, the power supply might be inadequate for the system or there might be a short. Don't press the power button to start up the system. Unplug the power cord so that the power supply will not be damaged. The next step is to open the case and search for a short. If you don't find a short, consider upgrading the power supply.
