PC Computer Motherboard Troubleshooting

Motherboard is a key component of the computer, plays a vital role in the the computer. If the board have problems and it will affect the entire PC computer system work. Here we take a look at the most common motherboard faults which during we use our computers.

Fault 1: no show boot

Computer boots no display, we need to check the BIOS. Motherboard BIOS store important data of the hardware, while BIOS is the more vulnerable part of the motherboard, easily be damaged, if damaged will cause the system to not run. This failure is usually because the motherboard BIOS damaged by CIH virus (of course not rule out motherboard failure resulting system can not run itself).In general, after the virus destroyed BIOS hard drive data will be lost. So we can detect the hard disk data to determine whether the good BIOS is damaged. If the hard disk data intact, so there are three reasons why no show boot phenomenon:

1. Because the motherboard has expansion slot or expansion card problems, Board did not respond to display when plug in expansion card, such as sound cards, etc.

2. the CPU frequency settings in the CMOS at motherboard Free wire jumper does not right, may also lead to no-show fault. In this regard, fault can be resolved as long as the clear CMOS. Clear CMOS jumper is in the vicinity of the Main Board of the lithium battery. The default location is usually 1,2 short, just change it to 2,3 short jump, a few seconds you can solve the problem. If users can not find the jumper of previous old board, just remove the battery, enter the CMOS settings to be displayed and boot off, then install the battery also reached the CMOS battery discharge purposes.

3. Motherboard does not recognize the memory, memory corruption or memory does not match will result in no show boot failure. Some of the old board more selective memory, Once plugged in the memory that the motherboard does not recognize, motherboard will not start, and even some motherboards do not give you any fault tips (tweet). Sometimes of course, to expand the memory to improve system performance, plugging different brands, types of memory can also cause such a failure occurs, so maintenance should pay more attention.
