Photoshop :: Laptop - Grayscale Is Blue!

I have a new Dell Vostro 1000 laptop, running Windows XP.

I'm the editor (copywriter, proofreader, layout person, etc., etc., etc.)for a quarterly journal for a non-profit organization. The journal is created pretty much entirely with PageMaker 6.5, with the photos being worked in PhotoShop 7.0. I know... XP and PageMaker 6.5 have some problems, but I never have or had this problem with my desktop, and the few problems I do have, I've managed to get around.

What's happening is, when I convert an image to grayscale in PhotoShop, it doesn't appear grayscale on my monitor... it has a blue hue to it... it also looks that way placed in the PageMaker publication. I'm sure it's just some simple setting on the laptop, but I haven't a clue what it is or where it might be or how to change it so that when I tell it grayscale, I actually SEE grayscale (not bluescale!). It's important that I see (at least relatively closely) how it will look in grayscale so I can adjust the contrast, levels, etc., as many of the photos are 100 years old and so need quite a bit of "playing with" in PhotoShop.
