Clock pulse generator circuit of the common mistakes and how to handle

NOTE:
Including an IC circuit and a quartz clock comes 14.3.
Just find the IC Quartz 14.3 is next to the clock IC.

Duties:
Generated 14.3 MHz quartz oscillator is 14.3 MHz standard, then the clock pulse generator circuit would get from standard quartz oscillator and then multiplied by a certain percentage to create different frequency clock pulse supply for the components of the motherboard.


Common errors:
Lost motherboard clock to complete paralysis. When the clock strikes take back your power fan does not boot.

How to check:
After checking on the mainboard as the main source of vCore, sources RAM, AGP, chipset North, South, the observed light CLK. If light is good clock pulse.

How to handle:
dry clock IC.
Instead try quartz 3.14 (3.14 to correct)
Replace clock IC (must correct numbers)
If after treatment, check to see bright lights CLK clock pulse generator circuit is already operating well.


Advanced error:
- In fact, the clock was at PCI slot (clk bright lights) may have found the clock to the entire department on the mainboard, such as CPU, chipset North, South, sound, LAN ...
- The inspection of the clock at the other positions require a "oscilloscope" and workers have been testing a new experience.
