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 :)
