Computer hardware knowledge to replace the motherboard without reloading the system method

Computer now has become a daily necessities of life, then how much do you know about computers? The following small series for you to organize some common computer hardware knowledge, quickly to learn!

Computer hardware, including all the physical parts of a computer, to differentiate between the data it contains or executes and the software that provides instructions for the hardware to complete the task. Computer hardware mainly includes: chassis, motherboard, bus, power, hard disk, storage controller, interface card, portable storage device, built-in memory, input equipment, output equipment, CPU fan, buzzer and so on.

Motherboard

　　The first step: do a good job of the main system backup (specific view of the actual situation of Internet cafes).

The Internet café uses the "Lenovo Camp protection system." After doing a good job, all the hard drive data of the machine, which is prepared as "amd+viakt600", will probably take an all-night time. Then find a pass through the machine, the boot into the system.

　　Step two: Start the modification.

Reminder: Must be logged in as an administrator. Uninstall the driver, go to "Add Remove Program" in Control Panel, uninstall all related drivers, and reboot. To disable ACPI, right-click on my Computer--manage--Device Manager--"Computer"--"advancedconfigurationandpowerinterface (ACPI) PC".

　　Step Three:

Right--Update drive--select "From list or position"--next--"Do not search my own choice"--Next--select "STANDARDPC" and then determine that the system will be prompted to restart the computer, select "No", and then exit, shutdown. Next, remove the hard drive and install it on a host of different configurations (mainly the motherboard chip configuration) and boot.

　　Fourth step: Install the hardware driver for the Internet bar on the motherboard.

Then enter Device Manager-"View"-"Show hidden Devices", all hidden devices are displayed, and are translucent. Remove hidden devices other than PnP driver and sound, video, and game controllers.

Then open Device Manager--"Computer"--"advancedconfigurationandpowerinterface (ACPI) PC"--right--Update drive--select "From list or position"--next--"Don't search my own choice"-- Next--Select "Advancedconfigurationandpowerinterface (ACPI) PC" and then confirm, reboot.

　　1, the hardware error detection

Due to hardware installation errors, incompatible or hardware damage, and other reasons, it is easy to cause hardware errors, resulting in light operation is not normal, heavy system failure to work. In this case, you can only find the cause of the failure through the BIOS beep code at post self-test, hardware replacement, or through the DEBUG card. But these methods, the use is very inconvenient, and the user's professional knowledge also requires higher, to ordinary users does not apply.

For this problem, now the motherboard manufacturers have added a lot of humanized design, to facilitate users to quickly and accurately judge the cause of the failure.

For example, many motherboards are now specially designed for the hardware power self-test failure of the language broadcast function. For example, Asus's "POST broadcaster", this feature is mainly from the W83791SD chip of the Hua Bang Electronics, with ASUS design chip combination. can monitor CPU voltage, CPU fan speed, CPU temperature, chassis fan speed, power supply fan failure, case intrusion warning, and so on.

In this way, it is better to maintain the best working state of the computer. When a system has a device failure, the POST announcer will use voice to remind the accessory to fail. In the hardware debugging alarm, some motherboard manufacturers have their own very unique design. For example, MSI Motherboard, with four LEDs to reflect the failure of the motherboard. While some motherboards simply introduced the debug debugging of the earlier years debugging technology, using a more direct digital withdrawal point fault.

In addition, many manufacturers also designed for the motherboard AGP protection circuit, in addition to the video card protection, the protection circuit also uses an LED light-emitting diode, to tell the user whether the failure caused by the video card.

　　Automatic detection of 2.CPU

Previous old motherboard, require the user to set their own CPU FSB, frequency multiplier and voltage parameters (usually through the jumper to set). Now the production of the motherboard, can automatically detect this

parameters, and then set these parameters correctly and keep them in the CMOS. When the CMOS power off, you do not need to open the chassis to reset.

In addition, now the motherboard also has the old motherboard does not have the CPU temperature detection alarm function. The CPU temperature is too high, can cause the system to work is unstable or freezes, even destroys the CPU and so on.

Therefore, the temperature detection of the CPU is very important. It emits warning detection when the CPU temperature is out of range. There are two kinds of probes for temperature: one is integrated in the processor and depends on

BIOS support; the other is external, which can be seen on the motherboard, usually a thermistor. They are changed by the temperature of the resistance to change their own value, so that the temperature detection circuit probe

The change of resistance is measured to change the temperature value.
