Black screen from new computer

[Biohel]

Hi, so I got this new desktop gaming computer just today I got all these parts and put it together :
Thermaltake Suppressor F51 Mid-Tower
Intel® Core™ i7-6700 Processor
GA-Z170X-Gaming 3 (rev. 1.0)
4096MB Gigabyte GeForce GTX 960 Gaming G1
Fury Series, DDR4-2133, CL14 - 8 GB Kit
Seasonic S12II-620Bronze
And I got this old monitor Samsung S22A300N (VGA only) So I had minor problems putting all together but I think I managed to do that, though when I run it, my monitor shows black screen nothing at all, and computer seems to be running.. Any idea?

got your pcie power on the gpu? monitor connecting to the gpu?

Since that card has no vga output im guessing you used an vga to dvi connector to hook it up with the gpu, if thats the case try switching to the other dvi port. If you hooked up the monitor to the vga output on the motherboard getting a black screen is normal since the graphics card is giving out a signal not the motherboard

I got PCI-E connected to graphics card and another cable with 6 pins that came with that video card, I do have an adapter but changes nothing, I tried connecting to the motherboard VGA and with adapter to graphics card.

Have you tried both dvi connectors on the gpu?
If both dont work try unplugging your gpu completley and connecting the vga cable to the motherboard

 

[Biohel]

No I have not, I got only one adapter, though I hooked up tomorrow with a computer mechanic so I got it packed, and I spend today like 6 hours trying to make it work, so I wont be unplugging it... And I don't think that would be the problem anyway..

a) you dont need two adapters, just put the adaptor out and put it in the second dvi port.
b) Your motherboard does not output a signal because there is a gpu connected to iy, if you put the gpu out of the computer (which takes 30 second) and connect the screen to the motherboard it should start outputting a signal

If there was anything wrong with the hardware you should be getting a error code on the mobo

Then how can my video card work ?

dvi to vga adapter to your dvi cable.

If you take the video card out, and the screen works when you plug it in the motherboard you will know that the gpu is the problem and not something else.
