pulled out an old laptop (win7) and ran linux livecd on it...surprised that linux detected the graphics card and was able to run several demanding 3D apps...

I originally thought the integrated gfx card was broken because Windows 7 suddenly stopped detecting it and reverted to generic VGA (and all 3D apps ceased working).


I even uninstalled and reinstalled the drivers + upgrade + registry cleanout -- none of which solved the issue.


There was only once when it reinstalled and detected...but after a restart it would revert to driver not found.


And opening the driver info always said theres a problem w/ the driver.  I had tried 20 different methods to reset it - none worked - card still undetected.


This happened a while back after win7 auto-installed driver update overnight - rolling back was no use.

Driver had worked great on win7 for many yrs without issue before auto-update.

But since Linux is able to detect the card, I believe the issue is w/ Windows and not the hardware.  

How to reset this so windows can detect the card? Technically it was win7 auto-update that seemed to screw it up.

Please download MiniToolBox  , save it to your desktop and run it.
Checkmark the following checkboxes:
  List last 10 Event Viewer log
  List Installed Programs
  List Users, Partitions and Memory size.
Click Go and paste the content into your next post.
Also...please Publish a Snapshot using Speccy taking care to post the link of the snapshot in your next post.

   Go to Piriform's website, and download the free version on the left.  Click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version. You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.

    After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
     Once inside Speccy, it will look similar to this (with your computer's specifications, of course):

     Now, at the top, click File > Publish Snapshot.

     Click Yes > then Copy to Clipboard

Now, once you are back in the forum topic you are posting in, click the ADD REPLY or REPLY TO THIS TOPIC button. Right-click in the empty space of the Reply box and click Paste. Then, click Add Reply below the Reply box.

Will the graphics work if you boot to Safe Mode?
