my computer has standard VGA adapter and not able to play pc games and the error is not able to create 3d scene when try to play games
Next time, One thread will do. Are you trying to play a moderately old game by any chance?
If its not broken, Fix it until it is
You just need to install the correct Graphics Driver, but as you have listed absolutely ZERO/NOTHING regarding system specifications, it is impossible to help !
Just to confirm, "standard VGA adapter" means no graphics driver has been installed. Windows is using it's built in generic driver which generally doesn't support 3D. You need to identify your graphics card (or integrated graphics chip), locate a compatible driver, then download & install it.
