system logs off automatically

Hello

My cousin has a computer which was working perfectly up until a few mins ago. It is a windows XP and it ask to click the user when he has to log on. When he clicks his name the desktop comes up for about 5 seconds and then the system logs back off and goes back to the choose which user to log on screen. How can this problem be solved?

Thanks

Could be malware or a logon script that logs off the account. Do a full malware scan in safe mode. Google cureit. Create a new account & try it out.

Is it a legit activated version of Windows? Windows XP will not allow you to log on if it's not activated within 30 days of installation.
