So I've just assemble my pc and every time I get it to boot it black screens in the BIOS after about 30s. At first i thought it was caused by inserting my usb stick with windows, because the first two times it black screened shortly after I put it in. But now it black screens roughly 30s after a successful boot every time regardless of usb stick or not. Also it will only boot to BIOS about a half hour after it black screens if I try to boot during this time I am meet with nothing but a black screen. any ideas? Could it be the monitor or is it more likely something internal?
here are the specs:
Asus Z-97 pro wifi
Gigabyte g1 gtx 970
i5 4690k
Seasonic X-650 650w psu

1. Open your case side panel, look for memok button in your motherboard.. turn on your pc then press hold memok until your system reboots.. (Memok is some feature of Asus board for self diagnosis)
If problems still there, you may try this:
2. Have you try bread boarding. Remove all the external connection, take out your board out of the case and put it on the motherboard box. Connect power supply, RAM of course cpu and cooler, kb/mouse.. Turn on your pc using the start switch on your board... try if you can go to UEFI bios..
Then check if you have excess standoff or unused standoffs that may short the solders at the back of your board or it could be screws are too tight.

try BIOS Flashback Button near the Power switch in your motherboard...
If you can use different pc, download latest bios for your motherboard at Asus Website, unzip and save into USB (better 2.0)...
Insert the USB drive to USB flashback port at the bottom of LAN port (rear of your motherboard)
..
On the board near press hold Bios flashback switch until LED blink few times, when light goes out means update completed.

Even flashback bios update still not working?
Is it black screen (monitor off) or your system is totally shutdown? please check also your monitor OSD setting.
On shutdown try remove the pcie power of you graphics card, connect your display direct to motherboard then turn it on again. Use only one ram, test it on one slot to another..

So I've gotten into the bios with just the mother board, psu,1 stick of ram, and a heat sink and it still goes black after about 30s. Its just the screen that goes black everything else appears to keep running. The CPU temp in the bios never goes above 30 degrees before the screen goes black that is. The light stays on on the monitor so the monitor is still running but the screen is black.

Did you disconnect PCIe power from graphics card or removed the card from motherboard? then connect you cable to your monitor..
Suspect as of now:
1. Cable - try different cable or use the cable on different PC.
2. Could be the Monitor - try set on-screen-display, i.e. Monitor power MENU saver is set to 30sec or adjust the setting 32-bit, etc.
3. Removed RAMs are defective, since you are running single ram right now.
4. We'll go back to graphics card.

I'm using a vga cable from the mobo because the graphics card doesn't have a vga output (running with out the card right now). On the new monitor i've tried both vga and dvi from the mobo and graphics card and still black screen after 30s. I tested the 30s screen on another computer with a vga and it ran fine.

That's fine.
Anyway, after all the works, we are sure there's nothing problem with your system, cpu, board, ram, gpu, and we can say psu as well.
About the monitor.. that model is an LCD:
Ensure you have tweak your Monitor Menu/ OSD like power save mode or something like that...
Anyway, once you completed the program installation, you can still test the new monitor if its good. Try connect your new monitor again to your pc either motherboard video port or graphics card. Turn On your pc, if the monitor turns black again, use a flashlight/torch and point it directly into the front screen. Try to look if you can see some image on the screen with your flashlight.. If its there and then disappear without the flashlight. It is most likely there is defect on inverter board or caps inside you Display... So RMA.
You may check the monitor is actually shutdown or when it appears failed - when the monitor goes black while system is running, is the screen appears the same as when the monitor is powered off? Little bright light into the monitor and check whether there is actually an image displayed. It's probably the backlight is failing.
