Check display drivers. If that doesn't work, use VGA connection. I was then able to see BIOS and the rest is history.

No, unfortunately I don't own another pc and I don't have any friends with compatible mobo's. Question, would the critical system LED for the CPU stay on if that were the issue? There are LED's for the RAM, CPU, GPU, & BOOT DEVICE.

Yes, I have... after installing it in the rig though.

(I built this using PCPartpicker... so I'm pretty sure but not positive that means they are compatible. Is this true?) Check if EVERY power cable is connected. Auxiliary power connectors included. Make sure the cable coming from your monitor is attached securely to the graphics card. Also make sure it is securely attached to the monitor itself. Make sure your PSU is powerful enough to power your complete system. Make sure your monitor works by testing it on a different computer. If you have both a dedicated GPU and an iGPU, try your monitor on both the outputs on the graphics cards as well as on the motherboard. Make sure all connectors and cables are plugged in securely, reseat if necessary. Make sure your RAM, CPU and GPU are plugged in securely, reseat if necessary. If the motherboard you're using has debug LEDs, check the error code and consult the motherboard manual to see what it means. If you have a debug speaker connected to the motherboard, note the beep sequence and consult the motherboard manual or this thread to see what it means. Try clearing your CMOS. (Yes, left the battery out for a whole 10 minutes!) Try booting your computer with only a motherboard, CPU and one stick of RAM attached (if you don't have an iGPU, plug in your GPU as well ). Make sure your GPU works (if you have a dedicated one), try it in another computer. Make sure your RAM works, try it another computer. Make sure the RAM is compatible with your CPU and your motherboard. Additional information that may be relevant I exchanged the mother board for a new one. I'm putting a pea sized amount of thermal paste on the cpu before installing the cooler. I've attempted booting w/o the storage device connected. I've tried booting with each stick of ram as a stand alone. I assembled outside the case, as well, to make sure the mobo wasn't grounding on something inside. I called ASUS help desk and they couldn't help either. Yes, I really did all 15 steps... multiple times. Big thanks to @HPWebcamAble for helping with my initial trouble shoot. I've built my rig twice now, with two different mobo's. After both builds, when I power on the comp, it goes through POST and stops at the BOOT_DEVICE LED. The manual simply says, "If any error is found, the critical component's LED stays lit up until the problem is solved." What are the odds that both mobo's are defective? I built the rig using PCPartpicker, even still, I went through to confirm that the parts are compatible. To my amateur understanding they are... HOWEVER, I admit I maybe wrong, as I am a noob. Honestly, I'm open to any (rational) recommendations at this point and I thank you all for your advice in advance!

I tried both steps one and two, problem still persists. Might I add this is my second mobo.

Unplugged the SSD, BOOT_DEVICE LED persists. Thanks for taking the time to troubleshoot, btw.

It says, "If any error is found, the critical component's LED stays lit up until the problem is solved."

I realize now that I should have been more specific. The BOOT_DEVICE LED turns on then stays a solid red after all the other led's cycle and turn off.

Noob question, I know... As far as I can tell, the MSI Radeon R9 380 shouldn't have a problem running the BenQ RL2755HM. However, I wanted to get a second opinion and confirm my assumption. Is this display compatible with the rig below? If so, will this rig be able to run at it's max on this display?

Thanks for the input! What do you think is crappy about the G1, etc? I find only positive reviews here: NewEgg & Amazon. I'm not opposed to spending the extra cash, as long as there is a legitimate reason behind it.

1. Budget & Location I'm trying to stay as close to $800USD as possible for the rig itself. 2. Aim I'd like to use this primarily for games like Battlefield, Fallout, No Man's Sky and the such. There will be some video capture and then light editing. Lastly, the usual downloads and streaming of the internet stuffs. 3. Monitors I'll use one display initially but I would like the ability to expand to three (or maybe use an ultrawide)… will that require me to upgrade the GPU or will the R9 380 suffice? Maybe crossfire? 4. Peripherals I most likely need a new keyboard and mouse. If you want to give recommendations, by all means, please share, but not necessary. Also, a note on the HD, I have 3 1TB’s for backup redundancy for anything not in the cloud. 5. Why are you upgrading? This is my first build. Just scrapped a 13 y/o IBM tower and thought it would be a nice excuse to start gaming on a PC instead of consoles.

Amazingly helpful post, thanks for the play by play! I'm building a rig for the first time and this post answered a lot of questions and made me feel a whole lot more confident in my choices. Thanks Windspeed36

I'm pretty sure, like myself, everyone here is sick and tired of hearing about 4K tv's after watching CES. I know it'll be another year or so before they start to come down in price. However with all the talk of "brighter displays," "nano-crystal tech," and "SUHD," I can't help but think this may be the pancea of display alternatives. What are your thoughts? Although I'm not a tech genius, I would appreciate, if you do share, that you please back up your opinion with some facts. Thanks!
