HELP! Display won't turn on after new graphics card installation

[joeygfx]

Hi guys,

In need of some help! I switched my graphics card from a GTS 450 to a Sapphire HD 7870 and now the display won't come on?

No signal is being detected?

I've made sure it's set into the PCI slot properly and the fans are spinning so I don't know what's going on?

I also changed/upgraded my RAM, that shouldn't be a problem right?

Can someone help?

Tried using all sorts of connects, HDMI to DVI etc - I don't know what to do..

Edit - Have switched back to the GTS 450, it works.
