I have a Leadtek 6600 256MB non-GT, im wondering what drivers do I need to install for it and the best drivers...........My moniter shakes (like one millimeter from left to right all the time) at 75 herts, its an 5 year old moniter (Delta DE-995 I think), Is the shaking caused by my video card or is it the moniter itself?? At 60 herts it doesnt shake but it hurts my eyes. Thanks in advance
