Widows XP failure on logging any user

[Guest]

My problems started when I was freezing my session of Windows XP. Everything
went OK until the final "Wait…" message. It remained displayed permanently
(>10 minutes) and no usual automatic power-off took place. At last I had to
use the PC switch button to switch off. All next attempts to log-in any user
started to fail. Having entered the correct name and pwd the mouse pointer
and keyboard have frozen a few seconds after clicking "OK". Mostly some tone
started to be reproduced permanently by the speaker. The tone differed a
little in particular attempts and different users; in some cases no tone was
heard.
I decided to proceed the repair procedure from the XP OEM CD. Although the
repair procedure terminated OK, no effort was obtained.
In spite of the described troubles it boots up fine in Safe Mode, even with
networking: it is possilbe to log-in any user and everything what can be run
in safe mode and I have tested was going OK. A new user added after the
repair to reckognize eventual corruption of former user profiles behaved the
same way as the old ones.
A full new installation of XP would erase all my settings and uninstall all
applications; I would like to avoid it. I believe, my situation can be solved
by repair of some Registry entry or something like that. Can anybody give me
an advice?

Make sure you have an up-to-date antivirus program, and a good spyware
detector. Lavasoft Adaware is free and easy to use. Some people
recommend Spybot Search & Destroy. Make sure you get the version from
<http://www.safer-networking.org/en/download/index.html>. There are
other versions, but many of them are fakes.

Start in Safe Mode, as you have said you can do. Log in as
Administrator. In XP Home, there should be no password. In XP Pro, you
must enter a password.

Once started up, scan for spyware and viruses. Delete any that you find,
and restart.

If that doesn't help, report back here.

Dear GateKeeper,
I checked the website you indicated and found it was the one I used to
update my SpyBot S & D 1.3 to the 1.4 version about a week ago. After update
the 1.4 version found some 20 threats, all of them were fixed. Accidentally
it as a few days before my present troubles started, but not immediately
preceding.
Nevertheless, I run the SpyBot again, but after some 18 minutes the result
was "No immediate threats were found". Fine for my PC in general, but
unfortunately not helpful for fighting my present trouble.
I am using the Avast antivirus last two years and I am happy with it.
Frequency of automatic updates of the virus database varies between weekly
and daily. Code updates are coming less frequently, say several times a year.
Having read your reply I guess, you still have another idea, am I right?
