How to determine the motherboard failure

How to determine the motherboard failure:

1, with the motherboard driver related to the motherboard driver lost, damaged, repeated installation will cause the operating system boot failure or cause operating system instability of the failure, you can open the "Control Panel--system-Device Manager" Check the "System Devices" in the project has a yellow exclamation point or question mark. Remove the yellow exclamation point or question mark item (you can do it in Safe mode), reinstall the driver with the motherboard, and reboot.

For example, motherboards using the Intel chipset will install the Intel Chipset Software installation Utility motherboard driver, and motherboards using the VIA chipset need to have a "4 in 1" drive to achieve better stability and compatibility.

2, the contact is bad, short circuit and so on the main board area is bigger, gathers the dust more place. Dust, it is likely to cause the slot and card contact undesirable phenomenon, when we can blow to the slot blowing, dust removal. If it is due to the socket pin oxidation caused by poor contact, you can have the hardness of the White Paper folded (surface smooth that facing outside), insert the groove to wipe back and forth.

In addition, the CPU slot used to detect the CPU temperature or the motherboard used to monitor the temperature of the chassis in the thermal resistor attached to the dust, it is likely to cause the motherboard to the temperature identification error, which causes the motherboard protection problems, in the cleaning also need attention.

When the chassis is disassembled, the electrically conductive material, such as small screws, may be stuck between the components of the motherboard to cause a short circuit phenomenon, which will cause "protective failure".

In addition, check the motherboard and chassis floor between the small copper pillars used to support the motherboard, whether the motherboard is improperly installed or chassis deformation so that the motherboard and chassis direct contact, so that the power supply with short-circuit protection automatically cut off power supplies.

3, and the motherboard battery related when encountered: computer boot can not correctly find the hard drive, after the boot system time is incorrect, CMOS settings can not be saved, and so on, you can first check the motherboard CMOS jumper is set to clear the "clean" option (generally 2-3), if so, please change the jumper to "NORMAL Option (typically 1-2) and then reset it. If it is not a CMOS jumper error, it is likely due to the motherboard battery damage or insufficient battery voltage, please change the motherboard battery to try.

4, compatibility problems encountered due to the motherboard design bugs or upgrade accessories when the new and old things compatibility problem (can refer to the previous installments of "* * fault should be how to judge" article, try to exclude it first, and after troubleshooting the BIOS setup, you can download the latest BIOS for the motherboard to refresh. In addition, the author also encountered the upgrade of the operating system caused by the compatibility problem later determined and motherboard BIOS aging caused.

Tip: Clear CMOS settings, can also solve some "inexplicable" fault, we may wish to try.

Tip Two: When the installed hardware is not recognized by the operating system, set the "PNP OS installed" (Plug and Play) project for the CMOS settings to Yes or NO, try.

5, the main board North Bridge chip cooling effect of some motherboards will be the North Bridge chip Heatsink omitted, which may cause the chip cooling effect of the system to run for a period of time after the crash. In this case, you can make homemade heatsink installed or add a good cooling effect of the chassis fan.

6, motherboard capacitor failure caused by the motherboard of the aluminum electrolytic capacitor (generally in the CPU socket around), its internal use of electrolyte due to time, temperature, quality and other reasons, will make it occur "aging" phenomenon, which will lead to the motherboard to reduce the impact of interference indicators of normal work.

We can buy with the "aging" capacity of the same capacitance, ready soldering iron, solder wire, rosin, will be "aging" replacement can be. In addition, the disassembly of the computer when the loss of tools may accidentally smashed the capacitor, should also check the exclusion.
