In hardware manager my 9500 pro comes up twice. One is 9500pro and one is 9500pro secondary. Is this normal? Also I sometimes get lines going up or down the screen, they are very very light and look kind of like getting bad tv reception. I got some artifacting in the raven shield demo too. My pc also froze twice (but it wasnt in a game) and wouldnt load windows untill i ran in safe mode and restarted. Could these things be caused by drivers? Because I didnt reformat after switching 3d cards. I thought it may be my power supply (because of the freezes) or overheating (because of the artifacts in RvS demo) but i'm able to run all my other games without artifacting and its never frozen during a game.
