Mobo: asus m5a99fx
cpu: amd fx 9370
gpu: nvidia 660ti
psu: 850w

I went to wake my monitor up a couple weeks ago and my computer was frozen. Then when I tried to turn it back on it powered up but wouldn't boot or post or anything. My motherboard as LED error indicators and it is the CPU light that's on.

Here's what I've tried:
Swapping out PSU, CPU, motherboard and RAM
Check for bent pins
Run with motherboard not mounted.
Check for shorts caused by screws
Resetting cmos by using jumper and removing battery
Reflashing bios with usb flash capabilities of mobo

I might be forgetting some things. Any ideas or help would be greatly greatly appreciated. Thanks guys.
