No screen after computer build help!

[Markus]

So I ordered a bunch of supplies to upgrade my computer during the blak Friday sale.

I bought a CPU/Mobo combination
A Rosewill 600 watt psu
8gb of ram
Evga GeForce 660

Now I've installed everything but when I go to turn the computer on I get no display I can hear my hard drive boot I can see the led on my motherboard come on and the fan on the graphics cards as well as the rest in the case are all spinning. I've taken the graphics car out and reseated it multiple times and I'm just stumped as to what I can do to get this to work...

What board is it, is there integrated video? Many boards with it default to the on board until it's disabled in BIOS.

I assume you already checked the idiot stuff. Like the monitor cables and power on to the monitor.

Do you see a bios screen?

If not I would say return or exchange the card.

I only unplugged the monitors from the computer and immediately plugged it back in after I installed everything. The motherboard I'm running is a MSI 970A-G46 the CPU is a amd fx-8 3.5ghz.

My thoughts are that the psu may not be supplying the wattage it's supposed to since the gtx 660 requires 450 watts though the psu is rated to 600...

Other thought is that the card is doa...

Neither of my monitors have a plug tha will fit the other adapters at the back of the computer besides the ones for the graphics card...

no integrated video on that motherboard... do you get any beep codes from the motherboard? Does the system post? so many questions dude. my guess is the cpu isnt seated correctly and the sys doeant post. your psu is fine.

600w psu is a bit small for your build(IMO) i would pick up a 750w unit and go with that, actually i would go bigger than that in case you want to go SLI later. But it might not be the video card thats the problem at all.

is the CPU power plugged in correctly? sometimes this plug looks like the pci-e power for video cards and can easily be overlooked.

it sounds like your pc is either not getting the proper power, is grounded somewhere to your case, or isn't plugged in right.

a 600watt should be plenty really. your graphics card isn't going to grab its full wattage unless its in a 3d application. for just getting the post / bios to show up and boot into your OS you shouldn't be coming close to maxing it out.

here's a thread on "black screen with no beeps"

the yellow highlighted post about halfway down the page includes some good basic steps you can take to eliminate the possible hardware issues

Had the same thing happen to me recently on a build for my wife's classmate. I didn't thought I had all the power plugged into the mobo, turns out I missed a power connection from the PS to the mobo and it came to life afterwards.

My guess is you forgot the 4-pin power connecter like brix did. It should be somewhere near the cpu.

Along these lines, make sure there 4 pin connectors from the PS are connected to the Video Card. From the pictures of the 660 video card there should be these connectors on the TOP edge of the card, toward the back (furtherst away from where the monitor is plugged in.)

Also note that one of the video ports on this card is DVI and the other is DVI-D. If your monitor is a VGA connector it is important to note that only the DVI port will work (with HD15 to DVI adapter) and not the DVI-D.

You know guys I may have made a rookie mistake and forgot the other power plug next to the CPU ill give it a shot when I get home from work.

[Markus]

Well I plugged in the other power cable and nothing happened. I looked at the mobo main power and it looks like the clip isn't on all the way could it be that the cable is just a wee bit loose?

I never removed my monitor from its power source I just unplugged itfrom my old graphics card and plugged it in wheni installed everything else. Also getting no beeps when it turns on...

[Markus]

I have the 8 pin connected now with no effect. The 660 takes a 6 pin which I do have plugged in already.
