I have trouble with my monitors / graphics card. Both monitors display nothing after installing new graphics card, ram and motherboard. Even though the fans is running, ect.

Tried with my previous pc, where I just replaced the graphics card. Got the same problem (No monitor input). Tried to put the old graphics card back in again, and black non-responsive monitors again strangely.

No BIOS beep codes. Tried clearing CMOS (Manually), if it worked it; changed nothing.

New Graphics card:
ZOTAC ZT-90301-10M GeForce GTX 960 2gb
New Ram:
HyperX FURY Series (2 x 8 GB) DDR3 1866 MHz CL10 DIMM
New Motherboard:
Asus M5A99FX PRO R2.0 (AMD 990FX, DDR3, S-ATA 600, ATX, 1 x eS-ATA, 2 x USB 3.0, Socket AM3+)

It doesn't seem to have a monitor cable (the new motherboard), it has USB and eSata, and then thethe usual (sound, keyboard, mouce). So it is connected to the graphics card.

I tried both with no result on my old pc.

Update: Here is a list of the motherboard cable outputs/inputs:
PS/2 mouse port
USB 3.0 ports 1 and 2
USB 2.0 ports 3 and 4
LAN
PS/2 keyboard port
Optical S/PDIF out port
USB 2.0 ports 1.2
External Sata port
USB 2.0 ports 5 and 6
USB 2.0 ports 7 and 8
AUDIO I/O ports

Solved it (I think)
Had to connect a 4 pin power input to the motherboard EPU (Eatx12V) slot. Not sure why this fixed it at all, however, or that it is the right way to do it (It is a 8 pin slot, not a 4 pin slot for one).
