ASUS M5A99FX PRO R2.0 Troubleshooting

[WhenRAR]

Hey there guys, so to start off, the other day I bought a new MoBo to replace my old and busted one, after I got home with it I started to put it inside of the chasis and move all of the parts from my old build into it (GPU, CPU, RAM, PSU) and everything was going fine. Once I got around to trying the first boot, I couldn't get any display on my monitor. On the board there are three LEDs (aside from the SATA led, but that's irrelevant) labeled as GPU_LED, CPU_LED, and DRAM_LED. The DRAM LED is under a little black button that says MemOK! which should be important later. The CPU_LED stays on constantly and is a bright red, I'm unsure if this is supposed to stay that way, but from other articles, I've heard that the LED is supposed to turn off after post. The GPU_LED which is slightly worrying me, does not turn on at all.

Here's a quick list of things that I've tried on my own:

-Pressing the MemOK! button above the DRAM_LED. Basically this caused the DRAM_LED to flash continuously (never stopped flashing until system was powered off)
-Re-seating the RAM into different slots (They are currently in the recommended slots for two sticks of RAM
-Trying the GPU in different PCIe slots (No success)
-Tried three different GPUs to see if I could get any display from any of them (ATI x1300, Nvidia Quadro 3500fx, AMD R9 270x)

P.S. Each of the GPUs that were tested seemed to work fine on account of the fans running when plugged into power.
P.S.S. The GPUs were tested individually without the others seated into any of the PCIe slots.

Thanks in advance guys,

By memory the LEDs being on indicates a problem.

I'd pull the CPU and check that there's no bent pins etc, and that it's correctly seated.

One thing about the MemOK button, once pressed it starts running through different settings until it finds something that works. It can take a long time and it may restart after each attempt.

Not saying that memory is your problem. I think at this point you start the basic troubleshooting. Check that all connectors are plugged in (power especially) even re-seating them. Try bare bones to get it to POST, graphics card, one stick of RAM, no bootable devices or ODD's.

Oh, I missed posting the POST trouble sticky: http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems

That should have been in my earlier post. Read it.
