Hi and welcome to the Gigabyte Forum.

The coloured LEDs that you refer to are quite normal as they should all illuminate and then extinguish as POST progresses.  Have you got a buzzer installed ?

Have you made sure all the power supply cables are connected properly eg the 24 pin to the motherboard , the 8 pin to the motherboard near the CPU and any required for the graphics card ?

Hi,
Thank you for such quick response. I'm sorry I don't understand what "buzzer" is.  Could tell me waht it is and where i can find it?  I did check all cables are connected properly.
Thank you very much

A buzzer is a small solid state device that ursurped the old speaker that was to give the POST beep codes. It is small and black and cylindrical about 60mm long with a couple of wires coming from the bottom and terminating in a small oblong connectort block often marked SPKR or SPEAKER. This fits onto two prongs of the motherboard that are situated down on the bottom right corner of the motherboard. There is a connector panel there marked FRONT PANEL or something very similar. The buzzer must be connected the correct way round as it is polarity concious.
