I just bought a new graphics card for my computer, but when I put it in and plug the monitor into its PCI slot, nothing shows up on the screen. When I plug my monitor into the onboardslot, I can log into windows, but under my device manager the only Display adapter is 'ATI Radeon HD 3200 Graphics'.

Also, I can see the fan on the new card spinning.

New Graphics card: Radeon HD 6670

When I try to install the drivers for my new card, windows brings up a message that says:
Files Needed
the file 'ati2myag.sys' on Advanced Micro Devices, Inc.
Installation DISK (VIDEO) is needed.

Type the path where the file is located, and then click OK.

Here are my computer's specs:

Windows XP Professional Service Pack 3 (build 2600)
Mother Board: ASRock A780GXE/128M
500 gig Iomega External HD
2 gigs of RAM
650W Power Supply

Is there something wrong with the card, or is it more likely my computer?
Thanks!

Seems to me that you need to check the BIOS...and enable the new video card, rather than the onboard.

Once the onboard is diaabled in the BIOS...the system should recognize the physical card, rather than the onboard. The correct drivers should then be able to be installed once Windows boots and the desktop settles.

I've tried going into my bios and disabling onboard, but I don't see an option to.
Under chipset settings I see:

Primary Graphics adapter: [PCI Express]
(other choices being Onboard, and PCI)

Internal Graphics Mode [UMA+SIDEPORT]
(other choices being UMA, and SIDEPORT

Do you have another Computer to check your new VGA? if yes please try it on another computer.
If your VGA still not detected on another computer to could consider to RMA that VGA as its still under warranty.

<<...plug the monitor into its PCI slot...>>

If this is a PCI-e card, then the BIOS must reflect that as Primary Graphics Adapter.

If PCI card, then the BIOS must reflect PCI as PGA.

Since the card comes in both flavors...you need to be specific.

So I wiped my drive and installed windows 7 on my computer, then successfully installed my video driver. My card is now working, kind of. My monitor seems to only get a signal from the card if I switch off my Power Supply, then switch it back on and turn my computer on. Also, games are running fairly slowly, even on the lowest graphics settings.
What can I do to fix this?
