i have a computer running windows xp home edition. some web pages, like windows update for example just come up blank. if i click windows update, the browser window opens, it acts like the page loads, and then it says done in the bottom left corner of the screen, but all i have is a blank white browser window. i checked for viruses, and updated to service pack 1a (which i had to download on another pc, because i could not access the microsoft download page). this computer originally had aol 9.0 installed, i uninstalled that. if i go to aol.com, and enter my username and password, then click enter, i get a blank screen. not sure what else to try.
