Help! My new build keeps power cycling and won't make it past the initial post beep!

post #1 of 7
Thread Starter 
I'm posting in Motherboards cause my current diagnosis is a bricked motherboard, but I'm at the end of my rope.

First, my specs:

Motherboard: Gigabyte GA-Z68A-DH3-B3 w/ F5 BIOS
CPU: Intel Core i5-2500k
RAM: 4GB G.Skill DDR3-1600
Video Card: XFX Radeon HD 6870 1GB
PSU: Antec Earthwatts 650W
Case: Cooler Master HAF 912

The PC was running fine for a couple of days. I fooled around with overclocking (had it sitting at 4.2GHz at stock voltage) but other than that I had just taken care of installing/patching everything and transferring all my media to new drives.

Last night I was going to use Darik's Boot and Nuke to wipe an old hard drive. I booted into it, but it only read my USB flash drive, not any of my SATA hard drives. I figured that was weird, so I wanted to exit out, but I couldn't find an option to do so. So I did a hard reset (held the power button for six seconds). Then everything went bad. Now, whenever I power up, the computer will power cycle weirdly: it turns on for about 1.5-2 seconds, shuts off, turns back on long enough to make it to the initial splash screen, where I get one post beep (successful post), then it pretty much immediately shuts down again. It does this infinitely: very short power cycle, then power cycle through the post beep, then short, then long, then short...

Since it was posting, and since it was precipitated by a hard reset, I initially figured it might be some power problem. Maybe it was overvolting for whatever reason. So I decided to clear CMOS. I shorted the jumpers, but it didn't fix the problem. I couldn't tell if the jumpers had worked since I couldn't get into BIOS (it shut off at the splash screen). So I pulled the CMOS battery. That still didn't fix it.

Still wanting to know if it was a power problem, I unplugged my graphics card, but that didn't solve anything. Then I ripped an old Corsair HX520W out of a machine and plugged up just the 24-pin and 4-pin mobo connectors, and tried booting with a different power supply. That still didn't fix the problem.

Now I'm convinced it's a mobo problem. I don't know what's wrong though. I was running DBAN, from a CD, fine up until I reset it. What could have gone so wrong that not even clearing CMOS fixes it?

Any help would be greatly appreciated!

Try to boot with only
CPU + 1 module of ram + GPU + 1 HDD and nothing more

"cmos" reset doesn't always seem to work! So I'd try doing it a couple more times "hoping I'm right" smile.gif

Make sure you get all the power out of the board by pulling it from the mains. And also holding the power button in for 10 seconds smile.gif

I'm really thinking if you can get the board to reset, you'll be fine!

Reset your Bios.

Cant explain why, I just know that when I had that problem with my computer, a BIOS reset fixed it.

I tried again. I pulled out the battery for 15 seconds, held the power button to fully drain it... nothing. frown.gif Now it won't even make it to the splash screen before cycling.

Ahh... Yet another Gigabyte boot cycle problem...

There is a Thread about this. http://www.overclock.net/intel-motherboards/1034724-gigabyte-p67-z68-boot-cycling-problem.html

Ya I think this is just the boot cycle problem, you can either wait for a bios fix or get another brand
