Hey guys,
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!
