collect information about functions such as temperature, voltage changes, and fan failures. These sensors are usually controlled by a hardware ASIC on the motherboard. As we have seen in the manageability discussion, such devices are crucial for managing servers and maintaining the normal running status of the entire network.ChassisThe chassis is equipped with a motherboard, power supply, fan, and storage devices.

XP system Front Audio No sound is going on
1, inserted in the computer chassis after the audio interface has a sound to explain the computer sound card and drive is all normal, as for the computer front chassis no sound is mainly 3 possible. First of all to analyze the structure of the front chassis audio interface, the front of the
, emitting noise. The solution is to take a blade in the scratch place gently scraping a few, increase the distance between the fan and the wall, to avoid both friction.
Eliminates Hard drive noise
The noise from the hard drive may come from its own vibrations, and this is not just about making annoying noises, but about the security of the hard drive. Because the vibration caused by improper installation is likely to damage the hard drive, so the horizontal installation of the hard disk mus
Often have DIY installed friends will ask, buy motherboard what board type motherboard good Ah, is the choice of the motherboard or small board? For such a problem, sometimes very difficult to answer, because the installed time, the choice of motherboard board type is not only related to the chassis, but also with their own needs. Today, the computer Pepsi Net small make up to specific and everyone to talk about the choice of the motherboard board typ
First, check the driver
First of all to check whether the graphics driver caused by the beginning of such problems, from the graphics card official website updated driver half a month or so did not occur, so the graphics driver caused by the problem is the first thing we deal with this kind of situation to consider.
Second, the inspection system
After the driver problem is eliminated, it is necessary to consider whether the system problem, the boot constantly press F8 into the Windows Adva
USB (Universalserialbus), Universal Serial bus, as the most popular peripheral interface, can support multiple devices on the same port, up to 127 devices can be connected to use at the same time.
As early as 1995 began to appear with USB interface of the computer, but the lack of software and hardware set support, so most of them are idle, Microsoft in the Winriows98 operating system to support the USB interface module, USB interface is increasingly widely used in computer peripherals.

Hard drive:
Normal switch machine.
On the boot, first open the computer's peripheral devices, such as printers, scanners, monitors, and then open the host.
When shutdown, close all applications, and then use the Windows shutdown program to shut down normally. Do not force the shutdown, do not suddenly power off. When the host is working properly, a sudden power outage is likely to damage the hardware, especially the hard drive, because the hardware is reading and writing.
