Standby Power LED (SB_PWR)
The motherboard comes with a standby power LED that lights up to indicate that the
system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should
shut down the system and unplug the power cable before removing or plugging in any
motherboard component.

Just so I have verify that I'm understanding everything properly, was the computer running fine before you shorted the motherboard? And when you say you shorted out the motherboard what do you mean by that exactly?

how did You short it out?? it is important to be clear on this point.
i would start by unplugging power cord, removing round battery on motherboard for 10 minutes, ensuring RAM is properly seated by removing, and reinstalling. if that doesnt work you'll need to go further into troubleshooting.

i dont know if that is hsorted out, or what, but you may be SOL. if it was me, id uninstall ALL but 1 RAM stick, and the CPU & cooler(even remove HDD or SSD). See if it boots into Bios. unless of course you can install another PSU, and see if that helps.

Most power supply's have a fuse that will reset. Just unplug for 10 min then try

yes, with this type of issue it is best that you start with using process of elimination, and begin with the simplest, least difficult steps, and move forward.
i would start by unplugging power cord, removing round battery on motherboard for 10 minutes, ensuring RAM is properly seated by removing, and reinstalling. if that doesnt work you'll need to go further into troubleshooting. Like uninstalling everything other than the CPU, cooler, and 1 stick of RAM.

Esd and shorts are hard to detect visually, take it to a shop to verify if the motherboard or power supply is dead, saves you from having to buy unnecessary parts if it is just 1 or the other.

Open the manual, identify the light to lock down what the issue is.
I think you are misusing the term "shorted out" ... a power failure is likely to cause many other issues even something burning out but that's not a short.
Turn off the machine and let it sit .... reset CMOS .... if you reach BIOS, reset all settings to defaults.
Call Tech Support, tell them which light is on and have them walk you thru troubleshooting procedure

Definitely is. It sounds more like a surge or something more ominous. I was under the impression @ first that he was shorting/jumping the pins to clear cmos, until i delved further.

pull everything out, reset the CMOS and on a bench test the board again to confirm its dead with a different PSU
CPU, one stick ram, video. Nothing else

I hate to say this but this is the very reason why I will never run a computer without a good APC UPS behind it that protects it from not only heavy power spikes (it sends the spikes to the battery and the battery don't care) and if the power goes out you have the ability to do a safe shutdown.
Once you get your computer back up and running I suggest you look into getting a UPS.

Get out some reading glasses, start with the motherboard and look for damage.
