ANSWER ALL THE QUESTIONS.

Question.1. Write the instructions one should follow while installing the newMotherboard.

Answer:It's more convenient to install the processor, its cooling fan, and the RAM before installing your new motherboard. RAM is easy: Lower the levers on the RAM slots, line up the notch in the module with the slot's protrusion, then press the chip until both levers lock.

After the standoffs are attached and the I/O plate is in place, install the motherboard into the case and make sure you align the back of the motherboard with the back of the case. As the motherboard is being installed align the holes in the motherboards with the pegs or standoffs.

Question.2. How do you to take decision on whether to replace or repair theMotherboard? Explain

Answer:If your motherboard fails, there are no options but to replace it or discard the computer. If your goal is simply to repair the system as inexpensively as possible, you can probably find a suitable motherboard for $50 to $75 that will accept your current processor and memory, unless the system is elderly.

But even if the current motherboard is operating

Question.3. How do you rectify the BUS errors? List out points one shouldconsider while connecting Bus to the various components.

Answer:The system encounters a bus error when the processor tries to access a memory location that either does not exist (a software error) or does not respond properly (a hardware problem). A bus error can be identified from the output of the show version command provided by the router if not power-cycled or manually reloaded.

If you have the output of a show version or show technical-support command (from enable mode) from your Cisco device, you can use it to display

Question.4. What is POST? What are the various steps performed by the POSTto check for resource availability?

Answer:When power is turned on, POST (Power-On Self-Test) is the diagnostic testing sequence that a computer's basic input/output system (or "starting program") runs to determine if the computer keyboard, random access memory, disk drives, and other hardware are working correctly.

If the necessary hardware is detected and found to be operating properly, the computer begins to boot. If the hardware is not detected or is found not to be operating properly, the BIOS issues an error message which may be text on the display screen and/or a series of coded beeps, depending on the nature of the problem. Since POST runs before the

Question.5. Discuss any five guidelines that we need to follow whiletroubleshooting the hardware problem.

Answer:Known-good parts: the troubleshooting silver bullet:Before we get into specific symptoms and fixes, there's one silver bullet that's guaranteed to get you past most of the support person’s troubleshooting script and right to what you want: the known-good part. That is, a power adapter, stick of memory, hard drive, or other component that has been plugged into another system and is known to be working properly.

To keep your system in good running order, follow these guidelines:

·         Do not enclose the system in a small, poorly ventilated area (such as a closet), crowd other large objects around it, or drape anything (

·          

Question.6. How do you solve of problem if you don't hear anything from thesound card?

Answer:Troubleshooting Steps:

1. First of all, put some Youtube song running in the background (you don’t necessarily have to choose this song :), it’s just one that I like), and make sure that it’s running on high volume.youtube volume

2. Right-click on the speaker icon in the bottom-right part of the screen.
