Le issue:
Worked for three months and then went to sleep and never woke up. It does not display anymore. It'll make start up noises via speakers (not mobo speaker). It's like the lights are off, but someone's home.

Le things I've done so far:

• 
  ■Multiple hard restarts. Nothing.
  ■Unplugged the graphics card. Nothing
  ■Reset the BIOS. Got me a couple of days but then went back to the issue.
  ■Bought a new same model mobo. Took three hard restarts to get it up. Reinstalled windows. Then reverted back to the issue.
  ■RMA'd graphics card. Reinstalled graphics drivers. Worked gloriously for all of one day. Then, see issue.
  ■Applied more thermal paste (some got wiped off during installation).
  ■Removed mobo battery and shorted CMOS this time. Nothing.
  ■Just breadboarded it with CPU, CPU fan, mobo, PSU on top of some poster paper. No RAM: three longs beeps (like it's supposed to, right?). One or more RAM in either slot: DRAM LED on for five seconds, off, then VGA light on for ten seconds, off.

I read that the motherboard could be toast? I'm tired of throwing money and parts at it. I could've built another computer... Please help. I'll buy you pizza.

Tried booting to a clean disk with only an OS?
Boot into safe mode if you can. If it's beeping , it's alive. Finger bang F4 to attempt to start in safe mode. Hopefully you see something.
A sudden thing like that sounds like a malware attack.

If you can get into your PC I would recommend deleting 'hiberfil.sys' that is your sleep/hibernation stored files. Something may have become corrupt. It is harmless to delete hiberfil.sys. it will regenerate next time you re-enter hibernation or sleep mode.
