  1. Did you install any software or hardware lately?

  3. I did install some software. But i erased it. Its still giving the error.
  4. when i open a dos box by typing in commmand.com in the run window, it opens okay, but it doesn't close it gives an xp end now window.
  5. Are you saying the software was the cause of the error, if so what was the software. Might help, if you don’t find a fix in Toey’s links.

  8. The software i installed and uninstalled was Freelancer.
  9. That doesn’t help! I tried to find something that might help, but had little luck. About the only thing I could find was <A HREF="http://support.microsoft.com/default.aspx?scid=kb;EN-US;q245184" target="_new">this</A>, but I don’t know if replacing the Command.com is a good ideal, because it’s not even concerned to WinXP.

    In Toey’s first link I notice <b>SUMMARY
    This article describes how to troubleshoot MS-DOS-based programs in Windows.</b> about half way down the page. I know you tried typing in the command.com, and it wouldn’t close, it wouldn’t for me either, so I don’t think that’s a problem.

    I also seen: >Prevent all programs from running at startup. Programs can run from three places at startup: the Startup groups, the Run and RunOnce lines in the registry, and the "run=" and "load=" lines in the Win.ini file. You can check these places as follows:< So all I can think is to follow what it says there, about the only chance I see to get rid of the error.

    Other things I might try would be to use <A HREF="http://www.helloduck.com/php/article.php3?id_article=364 " target="_new">RegScrub </A>sorry best I could find.
    Also,<A HREF="http://beam.to/spybotsd" target="_new">spybot</A> and <A HREF="http://www.vtoy.fi/jv16/shtml/regcleaner.shtml" target="_new">RegCleaner</A> be careful with reg cleaner, if I’m not mistaking you want to be darn sure you know what you are deleting or you could be in trouble.

  10. have you tried system restore ?
  11. Thanks for all your help. Ill keep looking. There are a few people i can talk to but i cant get in touch with them until monday. The problem doesn't effect the system. i just click close and everyting is fine. havent run into any problems with programs or the like.
  12. At least everything works good, I know it can be irritating. Now just figuring out where to delete the darn thing. Good luck.
