M_BIOS and B_BIOS blinking on my GA-Z77X-UD3H

[Koen1911]

Hey guys, as the title says, my brand new motherbord, just out of the box won't boot up. I'm not an amateur PC user but this is my first GIGABYTE and dualbios motherboard. The LED readout shows no code. When I turn on the PC a red symbol just blinks for like 1/10 second and then the readout is blank.

However , both the M_BIOS and B_BIOS LEDS blink, but not at the same time. When the M_BIOS LED blinks for a second, the B_BIOS LED then blinks for a second, and when that second is passed the M_BIOS starts to blink for a second again, and this continues over and over again.


Can anyone help me out ?


Thanks in advance

Is the psu EPS12v 8-pin power cable connected to your motherboard?

We can best help you after you create a detailed hardware list in the PC Specs portion of your forum profile http://forums.tweaktown.com/profile.php?do=editprofile at the bottom of the profile page or in your forum signature http://forums.tweaktown.com/profile....=editsignature.

Yes, that one is connected.

Also, i've updated my profile with the neccessary hardware.

Since I was on my iPhone just now, I didn't really have the freedom to provide such details.


Anyways, a more detailed explanation :

Just booting up the PC Barebones (CPU, RAM, GPU and Motherboard only) with the neccessary power connections of course, nothing happens. I get no image, no post, no bios, nothing. The LED Readout very quickly flashes a red digit/symbol), then is blank as well. The only thing that shines is the power on button, and the two M_BIOS and B_BIOS (Main and Backup) bios blink one by one, for about a second.

I haven't flashed the bios yet, it just came straight out of the box. The CPU (Core i7 2700K) also just came out of the box, and the graphics card has recently been tested. Although if any of those components would not work I'd probably see it on the LED Readout.

try with onboard graphics if you can just to rule out graphic card compatibility issue,are you installing ram in second ram slot and fourth ram slot from the cpu socket?

[Koen1911]

Tried with onboard video, no effect.

Tried only the 2nd and the 4th slot from the CPU, still no error code (completely blank) and the M_BIOS and B_BIOS LED's are still blinking one after another, for a second long.


Thanks for the help guys, appreciated.

Try booting with only one memory module installed in the correct slot.
If successful, install a second memory module.
For 3 or 4 memory modules, you might need to change some bios voltage settings.
You can create bootable Memtest86+ v4.20 disk for testing memory using a floppy, usb drive or cd/dvd.
Memtest86+ - Advanced Memory Diagnostic Tool, downloads are in the middle of the page.

You might need to test with your motherboard on a cardboard box, beside your computer case.
Do not put the anti-static bag under the motherboard.

It still isn't working. I tried with all 4 of my ram "sticks" but it seems the motherboard doesn't even get to the point where it checks if the ram is ok. There's no image on my TV, that damned dual bios led just keeps blinking. I hate gigabyte now.

Have you tried to switch the bios switch from the main bios to the backup and see if it would boot? Also have you tried clearing the cmos via jumper with PSU and cmos battery removed? Also make sure you have no usb devices connected other then keyboard and mouse.

[Koen1911]

Yes, I tried with the switch to boot the backup bios. When I flip the switch the blinking rythm is disturbed, but then just continues to blink.

I uploaded this video to show you what I mean with the blinking :
