I'd start by checking to make sure you don't have a massive spyware infestation. Download AdAware, Spybot, the works... Run each of them twice minimum and clear out anything they find.
After that, I'd make sure you don't have a viral infection. Make sure your antivirus program is up to date, and if you don't have an antivirus program, now would be an excellent time to get one. There's the freeware AVG, commercial AVG, McAfee (which I personally don't like because it seems a bit excessive on the resource use) and Norton. Pick one, make sure all updates are applied, keep making sure all updates are applied.
There's a very good chance that one of those two will clear up the problem. If not, come back and mention what you tried and that it didn't work and someone will take another crack at it.
OS: Windows XP Professional
First off, certain programs like Netscape and Windows Messenger won't open even after repeated clicks and only open for a short period after the computer is shut down and restarted. Secondly, IE isnt working right and will only load the homepage (it doesnt matter what the homepage is) when you open a second instance.
What could the problem be? There are more small problems that happen if they'll help. Could it have anything to do with a bad memory chip or something. Thanks. Help!
