Question about Gigabyte GA-8KNXP Motherboard

1 Answer

Gigabyte GA-8KNXP not going to POST

Not going to POST, not even reset works. Stopped suddenly while booting. Checked the PSU, Processor, Memory, Video Card with another mother board. All working fine. Replaced 3300uF capacitors that were leaky. Checked the 1500uF and 1000uF capacitors. What else to try? Any help is greatly appreciated, thanks in advance...

You can find leaky caps...
Anyways, those boards have very small inductors that look like caps and are used as pico fuses on most all peripherals and controller chips. Check that they are not blown and replace them with something from DIGIKEY or MOUSER
Also starting with the most simple, check that the power supply itself has not gone into SHOCK. unplug it from mains and TOGGLE the voltage selector switch, MAKE SURE it is back to 110 or whatever you need. 
I know it sounds weird but I have resurrected MANY PC's that way.
Other then that it sounds like you are well on your way to finding the defective component on your own. just thought I would throw in the fiew things that have caught me off guard in the past.

Machine was running..stopped suddenly..replaced power supply, cmos battery..nothing..absolutely no response what so ever..mobo is gigabyte 8knxp


You need to disassemble your motherboard specially the processor and the RAM. Once the RAM and the processor was removed you need to clean the motherboard. Re assemble the unit, put thermal paste to the processor so that the heat will absorbed by the heatsink.

Gigabyte motherboard GA-8KNxp will not power up


If you have just installed a new mother board, refer to your manual and double check your connections for pwr switch. If this is a machine you've had for a while and it just stopped powering up then your power supply is probably broken.

Monitor shut off, no BIOS post, no keyboard or mouse lights, will not boot


The best thing to do in this situation is to build your machine outside of the case, using the minimum amount of hardware,
Remove the motherboard and using only one stick of ram, the monitor, keyboard and mouse. short the power switch connector on the motherboard with a screw driver for a fraction of a second just to power it on.
If it starts up and gives you a "no boot disk" or "no Operating System found" at least you will know it's working and you can slowly connect everything else one by one to see whats preventing it from booting.
If it doesn't start like that, remove the power cord from the power supply and remove the mother board battery for at least 15 minutes, this will clear the BIOS and set it back to factory spec, now carryout the out of case procedure already stated.

Try another (Known good monitor). Or try you're monitor on another system.
Remove all memory except 1 DIMM. Double check all data cables (internally) & power cables. Remove the added video card. Try booting the system. Watch for the case LEDs to flash/blink, listen for hard drive spin up /cd-rom spin up. Lastly pull the battery & check with a volt meter. Bios battery should test no less than 3 volts. Post the correct MD rev.
