Motherboard suddenly won't detect installed RAM

Mobo: ASUS P8Z77-V Pro

I left my computer on sleep when I went out, I came back and it had shut down. When I tried turning it back on, I was greeted with the “Cannot detect any RAM installed” beep code (One long two short).
Since the computer wouldn’t even boot, I had limited options.
So I took everything out. I cleaned the front and back of the mobo, cleaned the RAM contacts, switched the positions (2-8GB; 2-2GB modules) and used that MemOK button. Nothing. (If you’re wondering why I have 20GB of ram, it’s because I use Autodesk applications and other similar programs.)

Is there anything I can do to remedy this issue? (Short of buying all new ram.)
I’m wondering what happened and am thinking there may have been a power surge or something similar, but that doesn’t really explain why only the ram modules are not working.

~Thanks
 
It's very possible that only the memory went bad, happens all the time. Try using known good memory and see what happens.

However, beep code for no memory installed is usually a constant beep for a couple seconds at a time.
 
I tried testing the memory sticks in every possible configuration, no dice. Since I don't really have a good way to test my ram (this computer is a MacBook) that option was out as well.
So, I ran over to the electronics store and picked up some new 2x4GB PNY Memory.
Plugged the new sticks in and got the same results - which leads me to conclude that the whole motherboard is dead.

Any suggestions for a comparable replacement? I built this PC from scratch, but have never needed to take out and replace the mobo before. Anything in particular I should look out for?
 
Update: Did a CMOS reset. Same results.
I finally convinced a friend to let me inside his PC, and my ram is working fine. So unless there are any other practical solutions it looks like a new mobo for me. Time to decide what to get.
 
You have to remove power cord from power supply, remove cmos battery, press and hold the power button on the case for a 10 seconds then wait 10 minutes. Then reinsert battery, reconnect power and try turning it on.
