I have just installed a brand new GTX 750 Ti 2GB Graphics Card and when I powered on the PC, the fans all turned on and a red light lit up but the output didn't work. I then plugged a VGA into the motherboard Graphics and tried to install the drivers but it gave me this message "please install vga cards of asus".

I also installed an extra 8GB of RAM, replacing the 4GB stick with two 4GBs.

My PC does not have a 6 pin power supply cable to fit in the top, so I installed it without this.. Could this be the cause?

My Specs are:
Motherboard: GIGABYTE F2A55M-DS2
RAM: 8GB
CPU: AMD A4 - 5300
