I have recently started using this computer we purchased a year ago (long
story....) and I uploaded about 4000 photos to the admins photo folder.

We have 4 users registered to this computer with separate log ins. Two
Admins and two read only to that folder.

I set up the screen saver for the slide show for all users from the shared
folder. Its set on Collage, rotating images.

The problem I am having is whenever it first starts showing the slideshow,
it flickers really bad for anywhere from 1 minute to an hour...it eventually
clears from the flicker, but its very consistent on the start up of the slide
show, and is EXTREMELY annoying...makes is impossible to watch the photo
rotation at all.

Does this mean my video card isnt capable of running the slide show
screensaver? Or is there some setting somewhere Im missing that will help
clear this? Or is it my monitor? Im not sure where to continue to look to
trouble shoot this. Ive exhausted everything I could think of.

My monitor is set at 1024x768.
