Radeon Mobility HD 4570 Not working after win 7 upgrade

I tried the driver from Acer, the one from ATI and the Mobility Mod (64 bit all of them); then Windows Update usually says it has a newer driver available, but it doesn't matter whether I install it or not, the 4570 won't start, always reporting error code 10.

I'm at a loss, I don't know what else to do except wait for a new driver from Acer or ATI--but this is frustrating and absurd, how can they launch a product without proper drivers? As I understand it, the Puma platform has been around for a while, and I kinda think they saw Windows 7 coming, or did they???

I don't know if this will help but Gateway released newer drivers for most of their ATI mobility line.

Do you think they might install/work on an Acer laptop? Or could it be a sort of sign that Acer might release updated driver relatively soon?

Thanks 'rflair' for your suggestion.. I have tried the new Gateway drivers and unfortunately the same issue... I am aware there is a new Bios on the Acer site (2.04)... anyone think this could fix the issue? I'm not that techy and have been a bit disconcerted around the warnings and dangers of flashing a BIOS in terms of trashing motherboard potential so this is something I have not tried... Acer support refused to comment as to whether it would fix issue and said if I do it is is my own risk... of course if I phone their premium number they will be able to fix the issue... erm I think NO!???? Does anybody suggest whether they think a BIOS update could have potential to fix this kind of issue?

Many Thanks,

Paul.

Funny, until yesterday (or the day before) there were two BIOS versions on the Acer support page, 3342 and 3344. I couldn't install either of those as the BIOS flash utility reported some error (corrupted source, or something like that).

I'm trying now with version 2.04 and I'll let you know.

Let's hope this works...

No luck (AGAIN!!!): the new BIOS won't install, reporting error 0x4d0 (whatever that means). I also tried running the flash utility as administrator, but it doesn't seem to change anything. I'm getting a feeling that there's some problem with Acer supplied bios flashing utilities under Win7 (at least the 64-bit version).

Maybe tomorrow I'll swap the internal hard disk with a spare one I got, try install XP on that and then flash the bios again... Who knows, maybe it'll work...

I don't quite know why it has worked this time as I have tried this previously as suggested on this forum (may be using I'm using a different driver this time though?) but I now have my 4750 gpu working on Win 7 64!

I was inspired by 'dam89' at the following forum to retry using Mobility Moder to 'mod' a gpu driver (ATI HD 3200 & HD 4570 in laptop not working - Windows 7 Forums)

I downloaded Mobility Moder (http://www.radeon.ru/downloads/modto...otNETSetup.exe) and also the the 'Windows 7 64 Bit Edition - Radeon - Radeon HD 4550 driver' from the ATI site (Graphics Drivers & Software).

I then unistalled all ATI software via control panel and to ensure all evidence of it was gone I ran drive sweeper (Guru3D - Driver Sweeper) to delete any thing left.

After a restart I double clicked on the downloaded driver so it extracted to C:\ATI\Support and cancelled it before it installed.

I then installed and ran Mobility Modder and using 'browse' located the driver folder within C:\ATI\Support\.... I ensured Disable UAC box was ticked and then clicked Modify. This modifed the driver.

Once done I disabled the 3200 gpu via Device Manager and then ran the setup file in the modified driver folder (c:\ATI\Support\[Driver Folder Name]\Setup.exe).

Once this had installed I was prompted to reboot and once restarted I checked device manager and both the 3200 gpu and the 4570 gpu (it shows as ATI MOBILITY RADEON 4530/4570) are running OK (NO 'CODE 10' & NO '!') :)

As with Sebs solution you can then simply switch between gpu's by switching displays (one is on a virtual display and the other is the actual display under screen resolution) or you can disable the 3200 gpu in device manager so the 4570 alone will be in use.

To prove it is working my windows experience index is now 4.1.

Thanks to all for your helpful discussion and information... I hope this fix works for you as well.

I did exactly this and my rating droped down to 2.7. Also both cards were running very slow after doing this. Any advice?

I haven't tried HDMI but I've been using the VGA output so perhaps it is the same. As with switching between the two cards, right click your desktop and choose screen resolution. With the HDMI connected, click detect and hopefully it should show an additional two monitors (so 4 in total now). You need the settings so that it duplicates your desktop on monitors 1 and 2 or 3 and 4. With the VGA on mine, it labels the new ones as "projector" so maybe it does something similar that will help for HDMI.

... erm that's strange... works for me fine... have you tried following the same process with some different drivers... i.e. the ATI driver on the Acer Support website for this model of laptop?... (available from: Service & Support )?
