Sounds to me like you've got a bug. Do you get any error messages at all?
Also:
1) What kind of AV and spyware removal tools are you using?
2) Are you applying your Windows updates and patches regularly?
3) What version of XP are you running?
4) Did you add/remove anything before the problem started?
After a crash when Microsoft Outlook Express 6 was running, mail account settings changed themselves - mail server became 27.0.0.1 and username became email address. Setting now reset to these duff settings whenever the machine is restarted. Tried adding a new account - both accounts now do it. Tried using the XP system restore to well before the crash - no effect. Anti-virus and anti-spyware updated and run.
Anybody got any ideas ?
