geforce gt 220 graphic card lags pc
Is the driver installed, that is the obvious question. A quick way to check is to go to start>right click on computer>select properties>device manager>display If there is an mark here the driver is not installed. If the driver is installed and its still doing reinstall the driver, if it does not go away after that, swap out the card for another and see if it goes away. If it does. The card is bad. Thoughts?
