'Don't know how to describe it' is a common problem with these things, but perhaps a screen print would help us.
Open Firefox, and either visit a site that shows the problem clearly, or you can goto Google and search a term that will give lots of images, eg I often search for just ISS , (the International Space Station), hit Search, then click the "Images" link at the top. This will list results in image thumbnail format.
Take a screen print, paste it into Paint and save it, then upload it to your favorite image hosting site like ImageShack, PhotoBucket, Flickr, etc. Make sure you can see the full image, then post that url web page address here.
Is it just browsers, or does this system have problems displaying other things, like photos, videos, etc?

I just reinstalled Windows XP Media Center Edition (Dell Pentium, 2007 vintage) on my daughter's computer, I got the chipset & the network card drivers from Dell Support, and everthing was fine when I gave it to her (although I had not finished Windows Updates, but I have now done so, and I think they are complete. BUT, the display in either browser is problematic (like some Active-X thing--I don't know how to describe it): graphics are not displayed properly, and everything has those rectangular frames, if you know what I mean. Windows updates, I think, are complete, Flashplayer is downloaded, Java is downloaded. Where's my troubleshooting on this, please?
