The computer is a bundle of several components. They cohesively act to help in the effective functioning of the system. They are perfectly architectured to meet our needs. They are very much robust and highly efficient. One of the great strengths of the PC architecture is that it is extensible, allowing a great variety of components to be added, thereby permitting the PC to perform functions its designers may never have envisioned. However, most PCs include a more-or-less standard set of components, including the following such as Motherboard which consists of CPU slot(s) and/or socket(s), Chipset, Voltage Regulator Module (VRM), Memory slots, Expansion bus slots and integrated functions. Other components include the processor, memory, floppy disk drive, optical drive, hard disk drive, video adapter, display, sound adapter and speakers, keyboard and mouse, communications ports and devices and case and power supply. Many computers sold from 2000 to 2002 were manufactured with defective capacitors. A leaking capacitor may not cause any system problems at first, but over time, as more and more electrolyte leaks out, the computer may behave erratically, lock up, be completely unusable, or even, in the most catastrophic cases, start to smoke and catch fire. A capacitor looks similar to a small battery. When it leaks, it looks similar to a leaking battery. While you have your computer case off, use a flashlight to inspect the capacitors. Look for any bulging or leakage from the top and bottom of all capacitors, know your computer and its components in order to have a great time with your system.
