also, I meant to ask....

can you refer to me a site or help me if you know...

I enjoy using the computer in the 1024 x 768 resolution while my family preferred the 800 by 600 resolution so we kept switching between them.

Now, I have a problem since the 800 x 600 resolution won't work properly anymore. Every time I switch, the screen slowly expands, then starts flashing violently. I don't know if something's wrong with my monitor, video card, or maybe some software..

Would you know whom I could ask about this?
