I'm shooting in the dark here and scouring web pages trying to find something about this.. You try a non-usb Keyboard or mouse yet? Something to try..
Niether USB or PS2 work.

And yes, all of the connectors are connected.

POST CODE "99" DEFINITION is "Super IO Initialization".

Thus it sounds like a CMOS problem. So I took the motherboard placed it on a wood surface removed the battery for 10 mins and jumped the CMOS. No help.

I'm pretty sure the mobo is defective. I have the same problem with my MSI 890GXM-G65; however mines won't even display anything on screen. It just keeps on saying no signal. The computer will sometimes boot up and work fine, but when doing a cold boot, the computer won't even post. I tried resetted the computer to no avail. At this point, I can only conclude that my mobo is defective or not working correctly when doing a cold boot.

I'm sure you tried the one stick of memory in all available slots, 1 at a time, as well..
Just going through the mental list of "what to do's".

Just an oddball thought... You've always tried booting with a keyboard and mouse plugged in, yes?
Try it with neither... Like I said, just an oddball thought.

I have tried doing so
Well rats... From what I've been able to dig up even MSI doesn't seem to know much about the mysterious code "99". It may be time to get a hold of them about an RMA.

Read it, says you tried one stik, not one stick in every available slot, one at a time. Just wanted to make sure..
I've had quite a few mobos run into an issue where one slot fails.
Regardless, good luck, I'm starting to feel an RMA coming.. :ohwell:

On a side note, I decided to remove the processor. The processor and the heatsink became merged together. What I mean when I say they became merged is that the thermal paste become basically a superglue between the heatsink and the processor (the FX-4170 naturally runs hot, thus, AMD has included an upgraded heatsink in it with better thermal paste). Anyhow, in order to remove the thing I could only get the mounting lever about a little over half way up. Therefore, on the back row, the pins bent a little (I would say there were making somewhere between a 80-85 degree angle orthogonal to the board). I took a credit card and a screw driver and straightend the pins, stuck it back in, still posted the same thing.

Last but not least, I read over the mobo specifications and realized that it was backwards compatible. The MSI 990FXA-GD80 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard supports the following CPU types/sockets:

FX / Phenom II / Athlon II / Sempron 100 Series
I realized I had a (working) AMD CPU HDZ955FBGMBOX Phenom II X4 955 Black Edition 3.2GHz AM3 125W Retail, thus, I mounted it on the MOBO... SAME CODE POSTED...

It must be the motherboard.

I tried booting up with a Corsair M60 and K60 and it just just won't boot. I would get stuck on the boot screen that is without the AsRock Logo. It has words on it during the boot.

Yea man, you can't kick yourself for not being thorough, you tested the shit out of it. Looks like a mobo issue imo..
GL with the RMA if you go that route.

Yeah I just hope when it gets there it does the same thing for them as it did for me... RMAs tend to be aggrevating at times. :shadedshu

4 years later and this is what is happening to me. After enjoying a working x99 motherboard for over a year. I wonder what the end of your story was?

I bought my current mother board in my specs. No RMA available, motherboard confirmed bad.

Does it cycle through codes and stops at 99 or it's the first code that appears ?
If it cycles codes means the BIOS is trying to go through the POST if that is the case you might be dealing with corrupt bios.
If it just stays at 99 would be more serious like hardware fault with the motherboard.
Super IO its a chip on the motherboard that controls the basic functions, for example the power and restart button and power leds are connected to it and bunch other stuff.
