Title: Starting problem with Gigabite P55 - USB 3.0
Post by: cenja on March 07, 2011, 08:10:19 am

I have a specific problem with this motherboard. When I try to start my computer my motherboard start for a second and shutdown. then herself is trying to start and same thing happens, just start for a sec (coolers start to spin for a sec) and stops. I try with a different power supply but same thing happens. My computer starts after a 10-15 times... what can be a problem???
My spec:
Gigabite P55 - USB 3.0
CPU Intel i5-760 Core i5
SAPPHIRE Radeon HD 5770 1GB GDDR5
Kingstone HiperX 2 gb 1600
650W ATX Chieftec CFT-650-14CS FULL

Sorry if my English is bad! :)

Hi and welcome to the Gigabyte Forum.

Firstly I would check the coooler is firmly fixed to the motherboard.

Next that there are no shorts to the chassis.

All of my coolers are firmly fixed... problem is that my motherboard receives power and run all my components just for a sec...
my computer is 6 month old... My problems started few days ago...
"Next that there are no shorts to the chassis." I think I'm ok with that...

The next thing to try is to clear the CMOS.

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least ten minutes before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Opimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.

Hi and welcome to the Gigabyte Forum Archi.

All the LEDs should illuminate at first when the board starts POST and then they should go out as it progresses.

Yes, my leds are on... I have reset my bios 2 days ago... my symptoms was the same... Yesterday was fine, started in first attempt. I think the problem was in room temperature, room was too cold. I don't have any more ideas... :(

That is probably the best thing to do for now just accumulate data on the issue. If you can see a trend appearing it can give you a clue as to what to look for.
It might be an idea to check your supply voltage too as that can fluctuate.

That is the first thing that cross my mind, but I just wan't to check your opinion... I'm not the first who experienced this problems... only Gigabyte motherboards are making this problems...

If what you say is true then it might be that the BIOSes are set a bit too sensitively.
