New ATI agp card, help with drivers!

I just received my Radeon HD 4670 AGP card for my old system, but can't seem to get any drivers to work for it.

I originally had a nvidia 6800 GT card. I went through the normal process I go though when changing drivers. I used the nvidia removal tool in add / remove programs. Rebooted into Safe Mode, used Driver Cleaner and cleaned out anything related to nvidia.

Rebooted and installed the drivers from the disc that came with the product from HIS. Rebooted, and got an ATI error pop up that said no ATI graphics driver is installed or the ATI driver is not functioning properly. And something to the effect of please install the proper drivers for the device.

So I went through the removal steps except this time removed anything related to ATI. But the card kept showing up in my hardware so I now had to tell windows to uninstall the device so I could start from scratch.

I downloaded the ATI hotfix for agp cards. Same problem.
I removed everything again. Downloaded the omega drivers. Nothing happened at all this time.
I removed everything again. Downloaded the newest drivers from the manufacturer. Same error popped up.

I've contacted the manufacturer but they haven't responded and I can't seem to figure out what is going wrong here.

These are my system specs:
OS: Win XP home sp3
CPU: P4 2.8 gig
MOBO: Intel model# D875PBZ
RAM: 2 gigs
PSU: 550 watts

I've read that windows netframework 1.1 is required, which I already have as well as the updates for it. Any help is greatly appreciated. If I can't get this thing to work, back it goes and back I go to my old card. Thanks in advance.

can you change it ? the sapphire 4650 1gb is also nice and i am using it on my agp 4x 845 momo with p4 2.4b northwood . also , due to the cpu bottlenecks you wont notice a difference with 4650 vs 4670 . my card has dvi to hdmi , dvi to vga and svideo to hdtv adapters . i am using it for light gaming and htpc . it is also chaper than the 4670 by quite a bit .

Windows Update ?

sometimes its better to let windows detect the card and let it install the generic video drivers an then restart and then upgrade. I remember something weird like that with the older ati cards. With a new agp card going in an old mobo there's bound to be a chance for conflict. I have a mobo with pci-ex and agp and its very finnicky.

Well it turns out the drivers are very finicky. I got them to work, well install I should say by simply using windows add / remove programs to remove the old drivers. Powered down. Installed the new card, powered up, installed the new hot fix drivers.

However, I can't play any 3D games, the entire system shuts off on me when a game loads. I switched the hot fix drivers for the latest drivers from the manufacturer, but end up with the same result.

The card says it requires a 400 watt or greater PSU. Mine is 550 watts, with 18amps on the 12v rail.

Here is what I did. Bare in mind that I'm had made a change from an nvidia card to an ati card. First I went into windows add / remove programs. I then removed all nvidia drivers.

Powered off the computer. Changed out the cards. Restarted. Loaded the current (9.10 i think they are) ATI hot fix drivers (the complete package express install).

However, when I went to run a game, my computer completely turned off as if the power switch had been flicked.

I had to actually turn the power off on my PSU, unplug it. Plug it back in, turn it back on. Then power up the PC. I then went to windows add / remove programs and this time uninstalled all ATI. I rebooted and installed the latest drivers from the manufacturer. However, this yielded the same result of my system suddenly turning off when a game loaded.

So I took the card out, put my old nvidia 6800 in, removed the ati drivers, swept them with driver cleaner in safe mode, loaded windows and installed the latest nvidia drivers. loaded all the games that crashed and ran without a problem.

I think the card is bad.

Now I use XP where as you have windows 7. There may not be compatible drivers for agp ati cards and windows 7, but that's just a guess.

I have an HD 4670 that works great under XP. Just installed Win7 on a new HDD and the ATI drivers are not applying. I have followed all the forum suggestions e.g using Safe Mode, Driver Sweeper, disabling the Std VGA driver etc, but no luck. The latest v9.11 Catalyst does not make a difference.
