The digital signing shouldn't matter as long as the driver is compatible. Sometimes a reboot and reinstall will fix those problems or you could try a different driver after modding the inf again.

just going to try that now....do you think it is worth downloading a slightly older version and one that is good for Vista ( and then run it it compatibility mode) or just download a different windows 7 one?

Strange thing is MS Windows site says that this card is OK

Sometimes the older drivers work better just depends on your system. Sometimes only certain drivers will work on certain systems so some experimenting with different drivers and modding the inf's is the only way to find which one is best.

Feel like I am starting to get somewhere.....sort of.

I used drive sweeper to completely clean then tried again with the same driver and modded file. This time though it showed as "Digitally Signed" but again on reboot, black screen.

What was different this time, apart from being signed is that the card was still in device manager with no reported problems when I ran in Safe mode. Previously it would have reverted back to standard VGA.

So....Going to try another driver version! Cant believe how hard this is for something that according to MS is certified for Win7..

But I am NOT going to let it beat me......and hopefully you will all help

Keep at it, but report back every so often to keep us up to date.

Why don't you try it the way I proposed seeing as it is signed /?,
it might work.

Maybe it was just all the driver pieces from the old drivers. Strange how the driver changed from unsigned to signed.

Will do that now

Bugger....didnt work....Tried the modded route with the next driver down on the list too. No good.

Before I go any further is there any chance the card could be damaged or does it deffo sound like a driver conflict somewhere ?

Are you installing this driver in compatibility mode?

Oops...forgot that. Should I ?

If you are installing it as per my suggestion, try it normal way, and if it doesn't work
do the compatibility way.


Compatibility Modehttps://www.sevenforums.com/tutorials/316-compatibility-mode.html?ltr=C

Tried the modded inf file way in comp mode....no joy.

I am going to have to continue this in the morning as I have run out of fags ...So frustrating as I have seen it working, all be it briefly.

Up at 6am to continue ??

Cheers for your help so far
