Running win 2000 pro, with Firefox or IE, when I run the computer for a while it tends to "load up" or something. It starts running real slow and my browser buttons become invisible also pictures in websites are not displayed, just text of what the picture is supposed to be,(even yahoo home page). I tried deleting temporary files, cookies and history and doesn't fix my problem. If I shut down and restart, everything starts fresh and works fine. This isn't a major problem, just quite annoying to constantly reboot. This is an old HP computer that was given to me, not sure what all is in it except I've got about 15gb of hard drive space left out of 20gb. Is this "JUST THE WAY IT IS" or is there something I can do to make it better?
