GA-Z68MX-UD2H-B3 - keeps on turning off and on

Hi,

I have the same issue with the system rebooting after a few minutes

My setup:
Gigabyte GA-Z68MX-UD2H-B3
Intel i5-2500K
4Gb RAM (2x2Gb)

I have swapped out most of the components and reset all of the BIOS settings. One thing I did notice is that if I remove the additional Gfx card, the reboot happens sooner. Not sure what that means but could be a memory issue as the onboard Gfx will use system memory.

FSMJR - Have you managed to get you system working yet?

the reason might be that those setting the ones I have listed above in the fist part of the paragraph I wrote are set too high from the factory as factory settings to better facilitate the overclocker and or for watercooling, phase changing purposes

Hi Folks, I have the same MB - exact same problem: Soon as you turn it on, the phase LED's will glow, the CPU fan will turn and then the whole MB goes dead! Well after struggling with the exact same situation here is the FIX.

* It is NOT the CPU.
* It is NOT the MEMORY.
* It is NOT the PS.

It is the MB and the BIOS.

Follow these steps for the Fix:
1) Remove all SATA Connections.
2) Just keep one Memory stick. (Just so we can get the guy going)
3) Ensure that there are no loose conenctions.
4) Press and adjust the heatsink that is right next to the CPU.
5) Notice the dual BIOS on the MB - just press it on the MB.
6) Remove the CMOS battery and put it back.

Now start it back up. It should turn on. If it does not just drop the whole thing from about a feet. Crap... something on this MB is loose.

Go hit the del key soon as you can and get into the BIOS.
Notice that this stupid MB will default to F2 BIOS when your OC fails.. and all hell breaks loose.

I got mine working the exact same way I described. I am not an idiot. Honestly this board is a piece of crap. Once the fellow gets going - its an awesome board. Starting trouble..

have a similar problem but its with the Z68XP-UD4 motherboard

Works fine and boots into W7 ok except if I go into the BIOS then on reboot it goes into a loop . Sometimes it will loop for about 7 times then finally it will post

also when I foolishly used the Gigabyte overclocking utility it froze the computer and had to do a manual shut off , ended up shorting the cmosand going into BIOS and selecting optimal settings and then after another loop it POSTED

now I stay away from doing anything related to the BIOS and have no problems but its a pretty poor effort from Google


edit : followed the guide on top and while the settings may be in different places I did find these

Disable full screen boot
Disabled USB Storege Function
CPU enhanced Halt ( CIE) - disabled
C3/C6 State support disabled - it says C2 C4 but dont have these in my bios
CPU EIST function disabled
Changed ACPI Suspend type to "S1(pos)" instead of S3

end story : I saved and rebooted and it worked first time
