When scrolling the web page, does the flickering happen only when scrolling with the mouse, or does it also happen when using Page Down/Up?
Mark
I have a HP Pavillion M70 monitor and every time I use the mouse scroll wheel the screen flickers and sometimes turn black completely.When I stop using the mouse, the screen stops flickering.
Also if I scroll an internet page, the screen flickers and sometimes goes off.
I am running Windows xp Home edition
Any Ideas as to the cause
