My Windows 7 upgrade tells me “no suitable graphics device found” when I attempt to play installed games.
I suggest that you uninstall the video drivers, then reinstall them. To do this, go to Start -> Search and type "devmgmt.msc" then expand "Display Adapters" and uninstall your driver there. In your "Programs And Features" (Start -> Control Panel) make sure any video driver related utilities are also removed.
Then restart. Once you boot back up, you should be prompted to install the drivers again, do so. Once installed, check your drivers for updates.
What you're seeing is a default VGA adapter driver being installed because Windows couldn't find a compatible driver to install
if you have nvidia then go to this link and do a scan
just run a simple test here http://www.systemrequirementslab.com/cyri/intro.aspx .
select the game title you want to play and run the simple test .
the test will tell you if your system has the minimum requirements for the game to play well ,
and if it does not pass the test for the selected game title , then what is lacking will also be told by test .
if your system passes the test ,
just revert back , and we can try some other steps ..
Hello, what operating system were you running before the upgrade? It is advised to run the Windows 7 Upgrade advisor before upgrading to windows 7 or a new installation. This tool checks your hardware and also software installed in your computer to see if it is compatible with windows 7. It also gives you advice on possible fixes if it finds something not compatible and also is able to fix some problems. Here is the link:
Is it an integrated card in your system? If it is, maybe your card is not compatible with the kind of game you are playing. If it is a discreet card, did you check if it is compatible with the games you are trying to play? Have you installed the most recent drivers for the card? You could uninstall all the drivers for your graphics card, restart your system and then install the most up to date drivers.
Final solution would be to get a different card compatible with windows 7 and your games and hopefully that would fix your problems. What graphics card do you have?
