New graphic card, no image

[tr4ce-11 5]

Hi there,

 

on friday I bought a new graphic card.

The Asus R9 280x 3 GB Top.

 

After replacing the old one with new one the system starts but monitor is still black. Also the Status LEDs on the graphic card are 'green'.

If I turn off the PC when there is no image and start it up immediately after shut down, it will start with image on monitor and I can play Battlfefield all night long with > 100 fps.

If I wait 2 seconds, I have the same problem.

 

My computer:

 

PSU Corsair 550 W

256 GB SSD

I7 3770

MSI Mainboard

8 GB DDR 3

 

BIOS Mainboard is up to date.

 

Thank you for your help.

Matt

do you have a big enough power supply?...how many  power plugs are on the card and are they hooked up?...to me, sounds like it isn't getting enough power...

550 Watt... 3 years old.

 

It needs a 6 pin and a 8 pin power cable from the PSU.

I hooked up a 6pin and a 6+2Pin Power cable.

I ran a 7970 and i7 on a 500w power supply. Unless it's an off brand I doubt that's it. That was my first thought though.

maybe try uninstalling graphic driver in safe mode and reinstalling it...all I can think of...

I've had similar problems and normally what solves them is unplugging everything from from the motherboard and reseting the cmos. Try that

Same for me. I usually just unhook everything and recheck connections
