Hi, guy dropped off his HUGE gaming rig and I told him I was no expert on hardware, but anyways it was working fine until about a month ago, now it won't power on. I pulled the 24 pin mobo power connector and stuck it in my tester, fired up all the lights fine, then turned on the pc and all the fans fired up. I pulled the gpu and one stick of memory and pulled the cmos battery and tried to power it up each time. Still nothing but a single glowing "start" button on the board. So is this mobo dead???

Video card not plugged in to PSU. Might start there.

Have you tried a BIOS Refresh? This board has a BIOS Flashback feature. Check the mobo manual.
Hold the "C L & R" keys down for 2 seconds to clear the CMOS.
With everything plugged in press and hold the "enter" key on keyboard for 2 seconds.
Failing that:
I would pull everything off the board including the CPU.
Reseat the CPU and go from there.
Plug in part A, try booting, plug in part B and try boot, repeat.
Are there any "beep codes", lights (apart from the one you described?)

if there's no beeps I would think you have a choice of motherboard or PSU. If you have a PSU of equal or greater power you can swap it in.
LOL I took the pic after I put the card back in before I plugged it back in, very observant!
Wish I did, all mine are pretty basic low end.
Wouldn't pulling the cmos battery for a couple minutes do the same thing? There's no beeps nothing, super quiet and sooo clean. But there are two lights on the back by the video ports. One is blue and is blinking bios and usb, the other is green with two arrows rotating.

Lots of bad reviews on that board, most of them have to do with faulty memory slots
I'm reading the manual now, I should be hearing some sort of beeps. Wish I had a comparable ps to swap. But it did pass with my tester and powers the fans fine just kills everything when I connect it's 24 pin to the mobo.

If you unplug the graphics and hard drives, your PSU will be enough to power up the motherboard for a check
Yes, psu tester is OK for checking if 100% dead but not if it is a failing psu. Had a psu a couple of weeks ago that lit up all the lights on the psu tester but wouldn't power on the computer under load. Dropped in a new psu and all was good again.
What known good psu do you have? You don't necessarily need the same rated power supply for testing purposes. For testing purposes/trouble shooting I would start as you have done by powering on with the minimum amount of devices connected. Disconnect everything from the board, all the harddrives, DVD, graphics card, use what known working psu you have and then power on. The motherboard appears to have onboard graphics via hdmi so you'll be able to boot into bios and see the result.
Beat me to it......
Yea, thats why I hardly ever use it
He came and picked it up and tried to give me $40 for my trouble, I ended up with $20 and directed him to a competitor with more experience and tools, I'm not going to buy a big power supply just to test it. I'm pretty confident its the board, thanks everybody!
Really? You don't have a strong power supply to test with. A reliable cheapie is under $50. It probably should be in your bag of tricks.
