new graphics card doesn't work

[Yigit Kececi]

I just bought gtx 760 for my computer and for the past 5 hours I been trying to get it to work with no luck. When I turn on my pc all the fans work and my pc lights up while I get no signal but my keyboard and mouse constantly turn on and off (the back lights go on and off), the only time I can get input is when I unplug the pci-e cables from the graphics card than a notification pops up on the monitor telling me to plug them in.
So I have no idea what to do at this point I tried reseting my bios, changing my ram slots, plugging my old graphics card hd 7750 which still works.
And also I have a msi 970a-g46 motherboard if that helps.

What is your PSU?

you need to tell us the rest of you specs in order for us to help you. it might be the psu, the 760 consumes 125w more than the 7750 so that might be related if your pc is a pree-built system (the retailers always go cheap with the psu)

Oh sorry I have a Rosewill Stallion Series RD600 600W ATX12V V2.3 SLI CrossFire Power Supply and AMD FX-6300 Vishera 6-Core 3.5GHz (4.1GHz Turbo) Socket AM3+ 95W Desktop Processor FD6300WMHKBOX
Also my keyboard and mouse were blinking because I had the ram in the wrong slot so now the keyboard and mouse light up when I turn on the pc for like 2 seconds than only the keyboard turns off and I still get no signal

Alright I fixed it apperantly I was plugging in the wrong pci cables to the graphics card
