Windows 7: Driver issue in windows 7 (ATI Radeon Mobility 4670)

07 Jul 2009   #1

Windows 7 (RC:7201 64-bit)
Driver issue in windows 7 (ATI Radeon Mobility 4670)

Quick summary of my issue:
I just bought a new acer (link) and proceeded to install windows 7 (64-bit) straight ahead. I must admit i made a bit of a mistake when i didn't check if the box it got shipped in contained any drivers or such (which it didn't to my surprise!)
Currently got experience with 32-bit win7, but not with 64-bit which I've heard had a rough time with bugs. Because my system is a 64-bit platform i suppose this might be one of the reasons for my problems. On a side note, this system is shipped out with both onboard gfx and an extra card (the ATI 4670 one)
But on to the main issue; Currently my problem with this system is an issue regarding my ATI mobility radeon HD4670 GFX card. (This is the drivers I've tried soo far:
Without any drivers, this is how my Device Manager list my display units. As you will notice windows update have already found some driver for it. But the Device will not start (This device cannot start. (Code 10))

After Installation of Driver software (Driver link #1):
I've just installed the drivers
Attachment 17057

Basicly the whole installation goes smooth, but after that, well, everything goes apeshift*
Attachment 17058

But in Device manager the ATI Radeon Mobility 4670 card actually is enabled, but still the Mobile Intel 45 Chip is the used display adapter.
(which has left me to think about trying to find some new drivers for this hardware, maybe that might help )
Attachment 17059

With drivers installed im now getting new options in the "Screen resolution" window if i push the "Detect" button
Attachment 17060

But here everything stops for me, no matter what i do nothing good comes out, currently i've been trying to fix this computer while watching dexter, needless to say after watching trough two seasons this awesome series im getting quite annoyed with the lack of support for this hardware issue, both from ATI's and ACER's side.
Theres probably a handfull posts/treads about this issue, going to link those closest to my issue here (remove them if its against the agreement)

Windows 7 (RC:7201 64-bit)

9 July - Got a new theory!

"Dual independent display support"

Something i read on the official acer page made me think, so this computer got two units capable of delivering display signals. Maybe theres an option to switch between the two units, but soo far i've yet to find any information on this.
so for now im stuck using the intel 45chipset as a display adapter.

update: Hmmm, horsepoo... the pictures i posted in my previous post is now goone, because i reinstalled win7 the hd got cleaned out soo pictures goone, bortevekk! ;<

Windows 7 RC

This worked for getting the new driver installed, but it doesn't solve the issue. I have successfully installed the new driver at least.

There were some tutorials out that was supposed to disable this automatic driver installation, but none of them were working for me with a clean installation.

But here is the workaround that I have found to be effective:

Tip   Tip
1. Download and install Driversweeper (and make sure you have the video driver that is to be installed downloaded)
2. Go to Device manager Right click my computer /properties/ device manager / and Disable any under display adapters.
3. Reboot into safe mode (usually F8)
4. Run Driversweeper and select your video drivers ATI (or Nvidia if someone else with Nvidia is reading this)
5. Manually delete any ATI folders that may be located at C:\ ATI and Program files (both X64 and X86)\ATI
6. Reboot again into Windows and install the new drivers then reboot once the installation completes.

By disabling the drivers in device manager instead of uninstalling them, it allows you to reboot without the WDDM installation taking over. You also should use Driversweeper and do a clean driver install any time you install Video drivers instead of just updating them, especially when switching between ATI to Nvidia as any leftover driver remnants from one brand will interfere with the other.

Edit this post has been edited to make it more clear to understand.

Windows 7

Indeed, this is the same problem I've been experience. I have only just installed Windows 7 (32) but I cannot get my Radeon 4670 to work. I have successfully downloaded and installed the newest catalyst software suit (9.9) from ATI/AMD and have disabled the on-board Intel adapter (in safe mode). However, when restarting there is an error message stating "No ATI graphics driver installed, or the ATI driver is not functioning properly. Please install the ATI driver appropriate for your ATI hardware." Nevertheless, device manager reports that my ATI adapter is functioning properly...

Hello I own an Acer 8935G with the ATI mobility radeon HD4670 Windows 7 64bits and I have the exact same issue as Kristoffach... Since I updated to Windows 7 my Games are working slower than on Vista !!! unbeleivable Spore is a lot slower than it used to be on Vista, Further more, Second Life will not start at all, it's telling me my video card is too old or the drivers needs to be updated and it wont start at was working fine with Vista... Tryed every upgrape possible ... I beleive the problem is Device manager the ATI Radeon Mobility 4670 card is enabled, but the Mobile Intel 45 Chip is seen as the default display adapter... I tryed disabling it, rebooting and re-enabling hopping the default would change to the ATI one...well it did not work... I will try Slovak21 solution and if it works or not will post my results

Windows 7 Ultimate 64bit

Hi guys, I fixed this tonight. I dont know if it will work for you guys but try this.

1. Download the following file - VGA ATi, make sure its the 173mb file version 8.64.4 Service & Support To find this you must select 'All Drivers' from the top right of the driver list
2. Uninstall both graphics cards through device manager
3. Restart the computer and both graphics cards will attempt to download the drivers automatically, the intel graphics card normally installs and becomes default
4. Restart the computer and check the device manager, the ATi card should now have a conflict showing
5. Install the downloaded Acer driver and restart when asked (the screen may display the windows background for a few mins dont worry be patient)
6. Restart when asked
7. When the computer has successfully booted up your ATi card should be the default thanks to the catalyst control centre.

Let me know how this goes?

Windows 7 Premium 64bits

Good News, I was able to fix my problem This issue seems to be related to the ACER 8935G, it is a problem with Windows making the Mobil Intel as the default, the Solution provided by hmoodie works perfectly well, the only thing you have to remember is: in order to download the VGA ATI 8.64.4 from the Acer web site, make sure you select "display all available drivers" otherwise you wont see the only version that actually works.

Yes, for some reason the only VGA driver download displayed when the "Latest" filter is selected is the older 8.64.3 version. Thus, you must selected "All" and scroll down to see the 'actual' latest 8.64.4 released on 2009/10/23 as opposed to on 2009/10/16.

I've yet to go through the configuration process that hmoodie has outlined. Hopefully it will work. Thanks!

Excellent, thanks for letting me know this worked. I have updated the process to reflect where to find the driver.

If you think I could or should change anything in the process let me know, I hope this can help some other people.
