Hi everyone...
Just bougt me a nice lovly mobo and a I5 3750K Water cooled system.
Runing 4 banks of 2gb 1600mhz ram.
And 1 590gtx with waterblock

have always booted up fine and worked like a charm. No OC as yet.
the system is only like 3 days old and want to have it perfectly stable before i o eany OC

Came home after work this morning,
and saw that my system was powerd off... it usaly in online 24/7

Hmm... weird... tryed to power it on... NOPE....
Pulled the side of my CM cosmos 2,
and saw that the mobo still was glowing its wonderful red, hmm.... pulled the cable to the psu... let it be out for about 10 minutes... still no reaction from the mobo... just turned on its internal red lamps around the soundcard and RoG logo and the buttons was glowing.

tried to start it from the Start botton on the MoBo nope... nothing.

Pullde the cable to the switches to the case, incase of the reset button or eanythin is shorted..

And yes it started up... for like 2-3sec
Then it reboots... It dont even have time to post eany error codes in the led display......

and it just runs in this lopp untill i pull the power...

things i have already tried:
reseting bios/cmos by battery
tested the RAM: OK
tested PSU at full load att all voltedegs: OK
Tested Removing the GPU 590 and runing on bult in hdmi: no change still no pic or boot
No waterleak

The only things i cant test is the mobo or the cpu, these are the only ones i have on socket 1155

1. Download the 1707 BIOS from Asus website.
2. Format a USB pendrive to FAT32.
3. Extract the BIOS file and rename the file to M5F.CAP.
4. Put the BIOS file on your USB pendrive.
5. Connect the USB pendrive to the white usb port.
6. Press the USB BIOS Flashback button/ROG Connect button for three seconds till the LED begins to blink, then release.
7. Wait till the LED stops blinking.
8. Power on your system.

Does it post now?
