Help installing AMD Radeon 8490 graphic card on HP Pavilion P7-1110

[jdpeterman]

Appreciate any help on this that anyone can give.  I'm at a loss at the moment.  Just got an AMD Radeon 8490 graphics card to put into the HP Pavilion p7-1110 desktop.  I have not opened up the back of a computer for probably ten years (used to do it, but haven't for a long time).  The card I got was new, but pulled from a workstation before going out, and came with no disk or documentation.  

I tried just opening up the back, and putting the card in the PCI-16 slot, but when I restarted the computer, the computer did not recognize either the old integrated graphic card or the new one.  When I pulled the card back out, it recognized the old integrated card.

From what I've been reading, there's a suggestion that I uninstall the Intel Integrated graphics driver before trying the install again, then plugging in the new card, turning the power back on and letting Windows 7 choose the drivers necessary for the new card, then it might work.

But what if it doesn't.  Then I don't have the drivers for the old and it's gotten me nervous that I'll be without any graphics at all and unable to use the computer.

Any suggestions?  Don't know why this has me this nervous, but I guess it's that lag time between dealing with a motherboard.

Appreciate any assistance, guys.

Nervous in PA.

Hi,

There is absolutely no need to remove the integrated video drivers.

Did you make any other modifications to your PC?

Okay, Thanks, Big dave.  Then why do you think it didn't work first time I tried?

Hi,

Did you make any other modifications to your PC?

[jdpeterman]

No.  None at all since I've got it three years ago.

Hi,

I see two possibilities.

1. The AMD 8490 is not compatible with your PC.
2. The 250 watt power supply in your PC is insufficient.

Try clearing the CMOS and see if that helps.  If not, then try the BIOS update that is posted for your PC.

[jdpeterman]

Okay, I'll give those a try.  Hopefully they aren't beyond me.  

I'm curious to why, if those are the two possibilities (incompatible to this pc/needs more power, specs seemed to indicate it was below 250w needed), as to why the integrated graphics card wouldn't work either when both were plugged in.

I assumed the original card would work?

Thanks,

JD

Okay, Dave.  I answered the second part of my question prior to trying the BIOS suggestion.  

The specs state that *Integrated video is not available if a graphics card is installed.

So I only have the ability to use the graphics card (if it's applicable) not both.

Okay, on to try what you suggest.

Hi,

Make sure that the card is fully seated into the PCI-E slot.

[jdpeterman]

Dave, ... I thought I'd try that before getting into the BIOS, but even after trying to make sure it was seated right, and I think it was, the same thing happened, no signal through, but the Radeon fan was spinning, so I guess that was working.  I downloaded the drivers and I think they loaded, so perhaps tomorrow I'll try that again, probably after I try your BIOS suggestion.  Got other things to do tonight and I don't want to rush.

I'll let you know how things go tomorrow.  Thanks for everything, Dave.
