This seemed to be the same issue I had with the first board... tried all of the same tactics on that one as well, just would never POST or show anything. Could I really be that unlucky to have had 2 bad boards? Do you guys really put up with "Just dont turn off your PC" as an answer to this problem????

First video is only 45 seconds so take a look and this will hopefully let you know of the exact issue that this thread pertains too.

I will RMA the motherboard, and possibly ask if I can exchange it for a different brand entirely. Probably an ASUS but need to find a good Z68 Motherboard in the £100-£130 price category.
I experienced this issue before with a failed OC. Like you guys, I had tried all the tricks out there (clearing CMOS, unplugging PSU, etc.).

The way I finally fixed it was by removing the CMOS battery and shorting the CMOS pins (i.e. connecting the two CLR CMOS pins together by touching them both with a flathead screwdriver). But instead of putting back the CMOS battery, I left it out and proceeded to turn on the computer and it booted. After it boots, you can go ahead and shutdown and reinsert the battery.

Let me know if that works.

same EXACT thing happening to me.

TWO Boards so far with this problem.

I press the power button then the system turns on for a few seconds, NO DISPLAY, won't POST, then turns off. Then on, and off. Repeats until I unplug power supply.

Is this a power supply issue or a MOBO?

After reading through the thread it seems as though this is a MOBO problem.

Why is this not GB's #1 priority? Does any board work? This is the second board that this has happened, and I doubt it's a processor issue. Should I just switch to asus or no?

If it doesn't even POST it may not be a boot cycling problem. Read 1) in the OP again.

Quote:
1) On a cold boot your motherboard only posts up to the "Memory Testing" (which is like the first 3 lines on your POST screen) line and then restarts on it's own. It continues to do this for a infinite number of times, theoretically. If someone actually wants to sit in front of their computer and start a count how many times it restarts, be my guest.
Shhhhh!

Hmm... I may or may not have just had my first boot loop. What Nahtzee describes closely matches what happened to my machine.

For a while now my machine has been producing high-pitched screeching electrical noises originating from the chipset area. This happens when the CPU voltage varies - like when you start up an application which uses a lot of resources. On my machine, it seems to make the noise whenever the CPU power goes down to around 0.116W based on what Dynamic Energy Saver 2 says (is that right? that seems awfully low for idle).

Apparently, based on my 10 minutes of googling, this is not all that uncommon with Gigabyte motherboards. The solution (well, 1 solution) was to mess around with the power settings, like disabling C1E support etc. So.. I was playing around with Dynamic Energy Saver 2 turning it on and off to see if I could hear a difference and my computer froze. I forced a shutdown by holding in the power button for a couple of seconds and when I tried to start it back up the machine behaved exactly like what Nahtzee described above - the only difference being that my machine has worked before.

In order to get out of the "boot loop" I turned off the power supply for ~30 seconds and pressed the power button a couple of times. Then turned the power supply back on and voila, it powered up no problem.

The electrical noise is now constant whenever my machine is idle, where as before it only happened sometimes. I'll probably have to RMA the board, but I might have to wait until after I move back to school.

Note: My rig is not overclocked, and you can see the parts list in my signature.

Alright, the motherboard has magically cured itself of the electrical noise.. I received an "overclock failed" message due to voltage changes - supposedly - even though I haven't OCed yet or changed anything. I should probably RMA soon. However, for the time being, I'm a happy camper. No more deafeningly loud noises. :-)

I believe I also have this boot loop problem. I first installed the z68a-d3h-b3 MB and did a fresh install of win 7 updated all drivers everything worked.. they I got a BSOD from a video driver from my crossfire 5770's so I thought ok maybe cards are going. reboot and bam it sits at the gigabyte splash screen and freezes then it will reboot itself and keep doing it.. changed out video card to an older one and it booted up so I was like ok it was just the GPU that was no good restarted windows and bam another freeze at the gigabyte splash screen.. is that just a bad MB since it has booted it's not my CPU right just purchased and I7 2600 so I hope it's not dead already.

I've just bought one of these mobos with a 2500k I hope I won't have these same problems. Would be a fresh install too with a z68

It looks like Gigabyte released a new bios on July 20 for their Z68 boards. Anyone using this yet?

I have a Z68X-UD4 supposed to arrive tomorrow, thinking about refusing delivery.

Lots of people (most) are using the updated BIOSes. I don't think you have anything to worry about.

I have an i5 2500K to go with the board, changing over from an AMD system. Not real comfortable with my decision though.

I am using SSD's exclusively for my system, except for a USB 3.0 backup - hoping to get the full potential out of the SSD's with Intel.
