Dear D-A-L: I had some problems with my graphics so I decided to upgrade the driver, but there once came out a small window asking me to install driver, or ask me next time, or do not ask me again for the driver, and I clicked on DONOTASK accidentally, and now that I want install the driver, there is no Graphic Adapter listed in the device manager, even tho I restarted the computer or clicked the "scan for new drivers" it does not appear, the current adapter is a default one, how can I make my windows to ask me to install the video driver again? thank you!

Problem solved, sorry for your time
