New PC - No screen signal

June 5, 2017 at 03:03:25
Specs: Windows 10
Hello :)

At first I'd like to say that english isnt my native language, so just to let you know if you find some grammatical mistakes.

My computer components:
- GTX 1080TI (MSI)
- Intel 7700K
- ARCTIC Liquid Freezer 120
- Asus ROG Strix Z270F-Gaming Mainboard Sockel 1151
- Fractal Design FD-CA-DEF-R5-WT-W
- Seagate FireCuda ST2000LX001 2TB
- Samsung MZ-75E500B/EU 850 EV
- Corsair CP-9020091-EU RMX Serie RM650X ATX/EPS
- Corsair CMK16GX4M2B3000C15W Vengeance LPX 16GB (2 x 8GB)

My problem:
The problem is that after i built the computer, there is no signal to my monitore, I have already tried it on two diffenet screens, but it always says "no signal found".

I also tried to put in my old graphic card, but there is the same problem, so i guess that the problem is not direct at the graphic card.

When i start the computer the mother board is active (shows lights), the power supply starts the ventilator for a second (which seems fine, because it's a semi active one).

When i look at the 1080TI the ventilators on the card itself arent running, and the lights are the same with and without activated on the power supply.

And for the CPU the cooler is activated and and running, like all other ventilators.

I really hope that you have some guesses what the problem could be and how i can solve it.
Maybe i have put the cables somewhere wrong .. but i dont know :(

Thanks for all answers :)

From the pictures I cannot tell if all is plugged in correctly BUT I can tell that you fully assembled your system without first doing a bench test. This is an important step in the building for a number of reasons. It allows you to confirm that the basic components are working and allows you to make the necessary BIOS settings so the remaining components can work as well. During the bench test you place the motherboard on a clean piece of cardboard (the motherboard box will do nicely) and install ONLY the CPU, CPU cooler (air cooler preferred at this point), one stick of memory only, keyboard, and plug the monitor into the motherboard (onboard graphics). Boot by touching across the start pins momentarily with a small screw driver (or plug in case wires for start switch if wires can reach outside of case). If it starts at this point you go into BIOS set up and make your basic settings time, date, CPU, Memory, and primary graphics (PCIe to primary graphics). Look at voltages and temperatures and make sure all is within correct range and the temps are not climbing after a few minutes. Shut down, add the remaining memory and restart. If still works, shut down and install your graphics card and switch monitor to it and retest. If this works, install motherboard in case and restart without any other changes. [If you used the stock CPU cooler to test, shut down, install the cooler block and hardware and restart into BIOS set up and monitor temperatures for at least 10 minutes. At idle you should probably be running at MAX the low 30C's on your CPU temps, if not then you have not applied the thermal compound properly or there is something wrong with the water system] Shut down, install your primary drive only (the one you plan to boot to) and optical drive, start and go into BIOS set up and rest your drive as bootable and select it as second in boot order and optical drive as first. Shut down and install remaining components except secondary hard drives (you install these after you have installed your operating system (Windows, Linux, etc.)), test, and set any remaining BIOS setting as necessary. You can now install your operating system.

You have to be a little bit crazy to keep you from going insane.

Excellent advice from Fingers. Unfortunately, a lot of people skip the bench-test process, presumably to save time, but then have to waste time troubleshooting to try figure out what they did wrong.

Did you try booting with the monitor cable connected to the motherboard graphics port? It's very possible that the integrated graphics is enabled by default. If that brings up a display, you would have to enter the BIOS, change the graphics setting to the PCIE slot, save the settings, then shutdown & swap the cable back to the graphics card.

I concur with the above , strip it down , start again, reseat everything outside of case

Alternatively try hooking up a speaker to the motherboard speaker terminal and listen to any beep code . Look also for LED sequences and read the manual to see what the potential sequence means
