One of the most important part of the computer is the Power Supply Unit or PSU. This device acts as responsible of converting, commonly in the Philippines is 220-240 Alternating Current Voltages. It will converted down to low level voltages called Direct Current Voltages of computer. Commonly rated as +12, –12, +5, –5, 3.3 DCV standard use to function the computer systems. Inside of this device it is built with variety of electronic components, such as the electronic circuit board and the exhaust fan serves as the cooler or the blower of the temperature to maintain the normal temperature of the electronic components, such as the transformer, capacitors, and transistors. The common cause of the failure of this device is the dust buildup inside. That will cause failure of the exhaust fan coil, because of the stoppage inside and this is because of the locking of lubricant. And this is the start of the weakness of the electronic parts that sensitive of over heat temperature such as the output capacitors that have only 150 degrees Celsius. If this happen to your computer it will cause to restart randomly and this will cause to corrupt and hang- up of the Operating System’s of the computer. That will cause failure of the HDD in the next days of using of your computer.
To avoid this unpredicted failure that probably cause of the burning also of the exhaust fan coil inside of the PSU, we need to perform a maintenance of the PSU by removing the dust buildup inside and check the rotation of the exhaust fan that will rotate freely counter clock wise.

The motherboard (MOBO) of computer is the foundation of the variety of chips to perform some lots of function of the computer. And one of the microchips is the Microprocessor Chips that mounted in the processor socket built in the MOBO. The motherboard is house inside the system case, that this system case simultaneously building dust inside. And one of the hardware where the dust buildup gather is the motherboard and together the processor mounting airblock or simply called processor cooler that cannot rotate exactly because of the dust buildup block on it. And this will cause to overheated the heatsink assembly then the thermal paste will dried up that will cause to not hold the processor and the heatsink assembly of the cooling fan or the airblock. This will cause of the malfunction of the computer because of the overheat. And the very will know symptom and error is the reset mode error in a moment of time. That sometime will cause to blue screen of death (BSOD) of computer that will damage the hard disk if the error not solve immediately.

Remember this is only a guide a help to you to learn as we do our best to pass the exam, so do your best to study and familiarize and memorize the hardware and materials of the computer. Not only that, you need also to learn about the assessment center, including the working area where the exam perform. You need to familiarize the equipment use of that working area including the specs also, such as fire extinguisher. The very idea is to visit earlier the assessment center or visit it before the day of the exam. Just study the table below how I write the specs of the computer.
