[*]Installed latest graphic driver
Well some cards can mess up games for example my computer use to run half life 1 perfectly, but now when i play it on my new card it lags up a storm. So my suggetion is that find a solution for your graphics driver.
Actually there is also the case of the power supply some cards require a certain amount for them to work properly. Mine barly works and how i know that is because every now and the nothing will come up on my screen so i have restart my pc.
