I have recently bought a Zotac GeForce 9800 GTX (
http://www.ebuyer.com/product/145610 ) the motherboard i am using is an ASUS P5N-T Deluxe (

The power supply i have is a cheap 1000w unbranded one (

I have had the pc running using a XFX Geforce 9600 GT xt edition (
http://www.ebuyer.com/product/142639 ) which worked fine, but i am using this now in another machine and the Zotac 9800 is to big to fit into it the case on the other machine.
anyway, this is the problem, i start the pc up, lights flash on the keyboard like they should, i have no speaker on my case unfortunately so i can't tell if its beeping or not if i leave the pc a few moments i hear the xp start up theme tune, but i never once get any signal to the monitor. I have checked all power cables which are finei have checked it is properly seated in the PCI-Express slot i have tried tightening the dvi cable screws with a screwdriver to make sure there is no lose conection and still i get no video.
when i put the xfx 9600 GT back in it works fine, (I'm using it to type this now)
if anyone knows how to fix this or if the card is faulty or if i'm just using incompatible parts please let me know, i have been trawling the net now for the past 3 days trying to find an answer.
