New Build, No Boot

[Rathlord]

Heya guys,

It's my first time building a PC and I have unfortunately run into troubles. Everything is together fine (as far as I can tell). All of the fans run, there are green lights on my graphics cards next to its power hookups, the mobo lights up when the computer is turned on... but I get no graphics output and the mobo is spitting error codes.

If my hard drive is plugged in, it gives code A2 (which points to a SATA problem). If my hard drive isn't plugged in it gives error code 99 (which point to a PCI-E problem). I'm really stumped and I'm desperate for help.

Things I've tried:

*RTFM
*Reseating the graphics card
*Clearing cmos
*Plugging in/unplugging my Razer keyboard and mouse (plugged into the USB 2.0 directly into the mobo, also tried the 3.0 slots on my case [and tried using the case slots as 2.0's by plugging it in that way in the mobo instead of the 3.0 slot])
*Changing RAM alignment between both blue slots, both black slots, only one in one black slot
*Crying
*Using back-up BIOS (BIOS B)
*Changing to a different PCI-E port with the graphics card

My build:

Antec GX500 Case
Asrock z97 Extreme4 Motherboard
Asus GTX 770 Graphics Card
Intel Core i7 4790k Processor
Seagate Barracuda 1 TB HD
G.Skill Sniper 16 GB Dual Channel RAM
Seasonic 620W Bronze PSU
Razer Deathstalker Keyboard
Razer Naga Molten Mouse
LG 27" IPS Monitor

If it has onboard graphics, try that without the graphics card.

It doesn't unfortunately.

We have a troubleshooting checklist for this type of problem. It should help you determine what's causing the problem. There's a link to the checklist in my signature.

Thanks for the link, I actually did walk through the checklist before I posted- still no joy.

Actually that's slightly different than the other checklist from this site I viewed. I'll walk through it in more detail, but I'm not keen on fully uninstalling everything to breadboard, especially since I can at least see everything is getting power.

I just figured it out. I had a monitor connecting straight into the mobo via D-SUB. This didn't work (not sure why, is this port only for if you have onboard graphics?). Plugging an HDMI cable into my graphics card ports directly lets me into BIOS and so far everything looks to be working correctly.

Yes, the motherboard video outputs are only used for onboard graphics. You have to use the video outputs on the video card.
