I built my 1st gaming rig yesterday

Sharkoon T9 Case
Intel Core i5 3470
8gb Corsair Vengeance
Cooler Master GX 550w PSU
VTX3D Radeon HD 2gb 7870

After plugging in graphics card i then put the hdmi in back of it and powered on,got no signal on screen,i then turned off and back on and got the same.

Turned it on a 3rd time and it worked,got to Windows is loading bar which then went onto Windows is starting. Within seconds i got 1 green line down middle of screen and 1 on right end of screen while the rest of screen was still on Windows is starting.

The screen went black and i got the no signal message on screen again,since then the pc will not get off the no signal screen when graphics card is plugged in. I am currently running the computer using the HDMI on the motherboard with no problems,i rang shop and they are picking up this 1 tomorrow and i had to buy another 1 while they process my refund for the current 1.

A shop local to me said my 550w is the problem and i should be running it with an 800 to 850w PSU whilst the shop i bought it from told me is talking rubbish and they linked me to the AMD site,i will post below what it said on their site.

My card requires 2 6 pins.

The below message is taken from the AMD website for my card

( 500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended7
600W power supply (or greater) with four 75W 6-pin PCI Express power connectors recommended for AMD CrossFireâ„¢ technology. )

Yeah 800-850 watts is a stupid recommendation. 550 watts would be ample, though Coolermaster aren't known for their quality. I'd say you just have a faulty GPU there.

Cool :-) A quality 550 watts will have ample power for your components and a solid overclock. Only if you push your hardware to absolute breaking point (overclocking-wise) would you want to step up to 650 watts.

What brand of monitor are you using, and what is the model number of it.
And also the screen size.?

On the back of your card you have Dvi ports.
One of the Dvi ports is a single link and only supports Digital output.
The other Dvi port supports both Digital and analog signals.

One is the primary display port.

If you connect a dvi cable to one or the other ports.
And then the Dvi port on the back of your tv monitor.

You will get a picture of windows desktop, and should keep displaying windows without it going black screen on you.

Ok, anyway it is the reason as to why you got the windows loading bar and just before windows desktop displayed the screen went black.
It switched from the Hdmi port to one of the Hdmi as the primary output display port ok.

So if you got a Dvi to Dvi cable everything would work as expected windows would be displayed on your tv monitor.
