What is the purpose of raised screw holes or standoffs installed between the motherboard and case? A motherboard is installed so that the bottom of the board does not touch the case. If the fine traces or lines on the bottom of the board were to touch the case, a short would result when the system is running.
To help orient the connector on the motherboard pins, look for a small triangle embedded on the connector that marks one of the outside wires as pin1. Look for pin 1 to be labeled on the motherboard as a small 1 embedded to either the right or the left of the group pins.
What should be done before a motherboard is removed from a case? You need to remove the side panel from the computer case. With the side panel removed, lay your machine on its side.
Which two components in a system might give out a loud whining noise? In case the power supply is not able to provide sufficient power to the devices then it will whine after the power is plugged up for the first time. At times there can be a problem with the power supply fan.
The system BIOS manages essential devices (such as the keyboard, mouse, hard drive, and monitor) before the OS is launched. the startup BIOS is used to start the computer and lastly BIOS setup or CMOS setup is used to change the motherboard configuration orsettings.
How much power is consumed by a load drawing 5 A with 120 V across it? Answer:The question is asking about power consumption, which is watts. The formula for this is: W = V *A. So 5A * 120V = 600 watts 3.
TLDR. Get the right socket for your CPU: You can find great CPUs from either Intel or AMD, but whatever CPU you buy, make sure that your board has the correct socket to support it. The latest mainstream AMD chips use AM4 sockets while current Intel 10th and upcoming 11th Gen Core CPUs work in LGA 1200 sockets.
Compatibility of 10th Generation Intel Desktop Processors
|Intel Core Processors Family||Chipset Compatibility||Supported Socket|
|10th Generation Intel® Desktop Processors||Intel® 400 Series Desktop Chipset||LGA1200|
There are different sockets depending on what generation CPU is supported. If a situation should occur where the CPU and socket aren’t compatible, the best case scenario is that the component won’t physically be able to connect with the socket, while the worst case may be irreparable damage to either system part.
Why are motherboards installed in the case using spacers? A motherboard is installed so that the bottom of the board does not touch the case. To keep the board from touching the case, spacers or standoffs may be used.
Before removing the motherboard from the case, unplug the power supply lines and SATA cables that are connected to the motherboard, and disconnect the wires leading from the front panel connectors.
Don’t set a tower case directly on thick carpet because the air vent on the bottom front of the case can be blocked.
Which two components in a system might give out a loud whining noise? for most systems, air flowsin from the front vents or vents on the side of the case that is near the processor cooler.
The BIOS begins its POST when the CPU is reset. The first memory location the CPU tries to execute is known as the reset vector. In the case of a hard reboot, the northbridge will direct this code fetch (request) to the BIOS located on the system flash memory.
