monitor screen delay

[tmonk]

I installed new video card in my Compaq Win ME pc and a new monitor. The picture is great ..........  exceeeeeeeept.......... when I go from one screen image to the next there is a long delay with a black screen (like a long blink) before the new screen image comes up. Maybe about 2 seconds. Also, when I use the scroll on the mouse there is a delay with a black screen until the screen image refreshes again. Any suggestions? Please help!!! Am a grandma of 2 and NO pc techie..... so please not to complicated...
