closing java application problem

Yesterday while trying to install java web server 7 I noticed that whenever I was closing a Java application my computer resets. This happends for every, even insignificant, java app. I removed the web server instalation and also the jdk and after reinstalling the jdk (1.5.0.7) it's the same problem. So, I would really enjoy any solution that you might have, besides reinstalling my Win XP again (which runs on am Athlon XP 3000+ Winchester core and MB Asus A8N5X).

Thank you for your time.
