GA-X58A-UD3R Wont Start

[PdqSnow]

My mobo was working until last wednesday. I've been reading a lot of forums' topics and never found the real problem. Now when I try to turn the mobo on I've been having some issues. The mobo turns on just the clr_CMOS light and two light near the RAM (The NB PHASE LEDs). Sometimes starts up but than shut down by itself. I've tested the RAM, HD and the Power Suply.

My config:

Intel i7 950 3.06 GHz
GA-X58A-UD3R
RAM Kingston 4GB DDR3 1333MHz
HD Western Digital HDD 500GB SATA3 7200RPM
ZOTAC  GTX 460 1GB GDDR5 256-bit
Corsair 850W (TX850)
Win 7 x64 SP1

ps: sorry my english...

 Don't worry too much about your English....we can always use sign language if it gets bad 

   I've tested the RAM, HD and the Power Suply. ... How did you effect (Do) the test ?

  Have tried as yet to reset the mothboard BIOS to it,s default state.....or for that matter have you updated the Bios ever ?

Hi

The first thing to do is to do and extended clear of 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 one hour 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 Optimised 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.
