Windows 7 - Radeon Mobility HD 4570 Not working after win 7 upgrade

Usually that error comes from when you choose a folder to install from instead of clicking on the .inf itself.

See if that helps..?

Hmmm. No, afraid not. Definitely selected the file and it gives the same message unfortunately

I just double checked the file. It's for x64. You downloaded x64 driver from ATI. Start over again with the x86 32-bit version for Windows 7.

If you download this link, and use my attachment with it, it should be good.

Extract from ATI's site, then overwrite the .inf with this one.

Use same .inf in the install process.

Thanks again. Still no joy though I am afraid - I followed instructions and installed your driver file, but this time it says that "Windows has encountered a problem - code 10 error, card will not start"

Very frustrating!

try ati modder and follow instruction in site
ATI MobilityModder - DriverHeaven.net

Did you copy it over the original one you downloaded from ATI's site, before installing from it?

Thanks Imagine - will try that

Hi torrent G,

Yes I did. It is getting a bit confusing now because I have so many driver downloads from ATI, but 90% sure I got the right one (even the amd site you pointed me too had multiple downloads)

The one I replaced had the same file name as the one you sent over

I'm getting very frustrated with this now.

I just tried removing both drivers and ATI's install manager, CCC, PowerExpress... any software relating to ATI so that I could reinstall it from scratch with some of torrentg's suggestions. Well, after removing the driver (half way through the ATI software uninstall) my screen went black, which makes sense if I've taken away the hardware that makes the screen colourful and pretty doesn't it, so yes, I'm an idiot for removing both at once. On the other hand, I took the power away and rebooted (it came on in 640 x 480) and Windows started trying (and succeeded) to install the cards. It seems that both card drivers are now working, as no error is reported. I have disabled the 3200 display adapter in device manager and still get windows aero in 1600 x 900 resolution so I guess it really WAS working? But then I enabled the 3200 again and the screen went to back to black... but on rebooting they're both working!!?!? PowerExpress is NOT running.

I reckon this is a problem with switching between the two cards as torrentg suggested with updating motherboard drivers. Otherwise it wouldn't have worked until I enabled the other one, would it? Unless it doesn't work at all, and it was just Windows (or me) being stupid.

But I don't actually know what I'm talking about, so I can only hope this stuff helps for someone who does know what they're doing.
