I installed this card in order to improve graphic resolurtion (not for games). Initially it works fine but within 15 - 20 minutes the screen becomes black, and Windows 7 gives a note that "Display card stopped responding and recovered". The whole issue does not take more than 15 seconds. Furthemore, the desktop background picture is lost and the desktop remains black until I restart. This is annoying and I could not find a reason for that. The card remains cold and nothing is wrong with the power supply of the computer.
