I agree you don’t need active desktop. I am guessing that you have either win 98 or 2000. If so that is partly your problem. The other is probably you have or had a virus which corrupted some of your files which makes them unstable. To fix that you will need to run some antivirus or spyware program (ex. Spybot, Stinger, Ad-aware etc.) However to properly diagnose I would need more details. But I hope this helps
