Z68X-UD4 Odd BIOS / Power Button Issue

[1967Typhoon]

Last night I had an issue with an OC setting not wanting to boot. 

I thought "no big deal I will clear CMOS".  I went to clear the CMOS and nothing happened.  I tried a few more times, and nothing.  I had to pull the battery for 30 seconds.  To get defaults to load.  That has never happened.

Here is the next problem I had.  Once I had cleared the CMOS, I went into the BIOS and got my settings how I wanted them.  I saved the BIOS, then rebooted and went back into the BIOS so I could power the machine down. (I have performance ram that wont boot on defaults).  For the past five years, I have been able to press the power button on the case to power down when I am in the BIOS.  Now when I press it, the screen goes black but the machine stays ON.  This causes the BIOS to go haywire and need a reset.   And then I have to pull the battery and wait 30 seconds again.

The other thing I tried is to power the machine down while in the BIOS with the power switch, and guess what?  IT MAKES THE BIOS NEED A RESET.

I have flashed the BIOS, and it still behaves this way.  Is this board done?  I have never had an issue like this with any board over the years.  I plan on ripping the whole thing out of the case tonight and trying it barebones with a different PSU to see if that may have some effect.

Maybe you need a new battery.

Put in a brand new battery last night.  Old battery read 3.17v on my meter, brand new battery was 3.27v.  I doubt it was the issue, but I put a new battery in anyway.

My main problem is not being able to power down in the BIOS from the power button.  That is a totally new issue.  That is the main issue preventing me from swapping ram sticks.

I REALLY don't understand why more BIOSes don't have a "Save and Shutdown" option.  It's really really stupid.

You should have this in the bios unless you are using the UEFI bios then you might not.

This is in Power Management.

Soft-Off by PWR-BTTN

Configures the way to turn off the computer in MS-DOS mode using the power button.

Instant-Off - Press the power button and then the system will be turned off instantly. (Default)

Delay 4 Sec. - Press and hold the power button for 4 seconds to turn off the system. If the power
 button is pressed for less than 4 seconds, the system will enter suspend mode.

I swapped PSUs on my lunch break and now the board behaves as it should.  I am going to try cleaning all of the connectors on the old unit and try again.  If that fails I know the PSU is shot.  Thanks for the help.

After a few minutes of it behaving nicely, the entire board powered down for no reason.  BOTH power supplies check out OK.  I can get the board to power back on if I use a low power GPU, but when I put my R9 290 in, it won't even attempt to boot when I press the power button.

I'm thinking the board is shot.  In all honesty I thought it was a tremendously underwhelming board considering how much I paid for it new.  It always hated RAM, it couldn't OC very well, and the BIOS is trash.  Adios, Gigabyte.

What PSU you using if it doesn't have enough amps with R9-290 it could be using all the amps up. Those card could be using as much as 30 amps a lone. Plus if the computer is working with the other GPU then it isn't the board. If the board is bad it is bad.

I have both a 750w and 650w PSU I am using for testing.  Both are high quality units.

Just an update:

I pulled the CMOS battery again overnight, and got it to boot to the BIOS.  I saved defaults and loaded windows no problem at all.  Thinking I had finally gotten this somewhat working, I shut it down in windows.  After shut down I tried to boot again, and it once again did not boot into BIOS.  It just gave me a black screen with all fans running.  I am going to hook up a speaker now and check for any beep errors.
