Problem - New Media Center - Loss of Display!

[Neo_nick]

Hello again!
Im hoping one of you members out there may be able to point me in the right direction!

I had an old HP pc here which i decided to tunr into a media center

Installed xp media center - OS is working fine as long as my tv tuner card isnt installed!
As soon as i plug in my pci Hauppage HVR1300MCE into my motherboard and power up the pc i get no VGA output on my monitor.
As soon as i pull it out and reboot its fine!

Any suggestions - i cant even see bios as the screen just wont turn on when the tuner card is installed in my P4 2.8GHZ, 2gig DDR, 2 IDE HDD, 256mb 7600 gt Vid Card

Hoping some one can help!
Nicko

Set the AGP Aperture in your BIOS to either 64MB or 256MB. Do not use 128MB.

nVidia 5xxx/6xxx/7xxx AGP cards and Conexant 88x TV cards get a resource conflict when AGP Aperture is set to 128MB.

Unfortunately i have no setting for this in my bios
I can only choose wether i use agp/pci video card - apart from that there are no other options

Any help would be appreciated!
Its definantly a 7600 256mb gs vid card!

Im considering just going and buying a new mb and cpu as the one im trying to set it up on is quite old - which i would imagine is part of the problem

I Just tried this card in a new pc with an asus p5kc mb and dual core processor with 2gb of ram, Asus 8500 GT 512mb card and it does the same thing!

It kills the VGA output - Anyone have any tips or pointers?
Is it a possible dud card?

ended up building a new rig with some new cards
Ill come back to this one later!
Could it be possible that i need a bigger psu in the older rig?
