Logging in then logging out?

[eibhrum]

I am having problems with my laptop (HP Pavilion zv600) which includes Windows XP Home Edition SP2.

After "logging in" in my user account, it suddenly logs off. It always happen everytime I could access my account in my laptop.

Before, I don't have any problems logging in my account.

By the way, I do only have one (1) user account and the Guest account is not seen in the start-up.

What shall I do?

Don't post the same question in 3 different areas. This will confuse you and anyone else trying to help. I am going to lock the other two, so watch here.
