Video Card installation problems HELP!

[SpyChaos]

So I bought a new graphics card and PSU to support it for my HP media center PC running Windows XP with service pack 3. The PSU works great but the card isn't happening well. My motherboard has on-board graphics which I'm fairly certain I'm disabling correctly (the graphics don't change into what they look like in safe mode) when I disable them in device manger. When I do this and shut down to install the card in a PCI-E x16 slot on my MOBO and start up again, the computer's fans go full blast (including the one in the card) but the monitor doesn't even detect input in either the cards output or the MOBO's VGA. The computer powers but doesn't detect the card at all.
 
   ASUS P5LP-LE (Limestone)
   Intell Pentium D 820
   1 GB DDR2 RAM
   CPUID tells me this is my on-board graphics: Intel(R) 82945G Express Chipset Family    224mb
   SAPPHIRE 100289L Radeon HD 5670 (Redwood) 1GB 128-bit DDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card w/ATI Eyefinity

   
My research has told me that ASUS made this MOBO for HP so its never been updated or really given much support. PLEASE HELP!

Have you enabled the new card in the BIOS

Have you enabled the new card in the BIOS

What?

1) You need to disable on board video in bios
2) Then install the correct device driver for your new video card

[SpyChaos]

The only Video Card options I can see in there are to select an automatic plug and play, options to change the on-board's memory allotment, and whether the main input is PCI or AGP.

[Allan]

Have you installed the video driver for your new card?

[SpyChaos]

I've tried but every time I do there's an error. The directions that came with the card say to install it then do the drivers.

[Allan]

And the error is........? ? ? ?

Well the website has 3 downloads that are more up to date then the discs but I'm not sure what they are. http://www.sapphiretech.com/presentation/downloads/download_index_01.aspx?psn=0006

What is the video card you are trying to install?

SAPPHIRE 100289L Radeon HD 5670 (Redwood) 1GB 128-bit DDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card w/ATI Eyefinity

Click on the link for the XP driver, download it, install it: http://support.amd.com/us/kbarticles/Pages/Catalyst-driver-for-Radeon-HD5670.aspx

[SpyChaos]

Downloading it now. Its reassuring seeing something I haven't tried over an over.
Also, 2 of the gold pins on the card that go into the slot to transfer info are gone. Is that a big deal?

If it's not detecting the new card, don't worry about the drivers.
You may have to set onboard memory to 0MB and/or main input to PCI (which may include PCI-e).
