Windows 7: Can't logon

Can't logon

So... this morning when I started my computer, I couldn't log into my user account.

It is password protected, I typed in my password, hit enter, then it seemed that my desktop is loading (screen went black), but instantly I was throwed back to the logon screen... (and again, and again)

After this I tried to boot up windows to safe mode. In this case there was no problem with logging in.
I made an other user account, logged in with it (to normal mode).
I modified the password of my original account.
For some reason that solved my problem, so I could log into it.

I remember that once I logged out and back without a problem,

But now (after using my computer for a couple of hours), here is the issue again!

Now I deleted the new password, and it is doing the same thing (seems loading, screen goes black, and throws back to logon screen), just without asking for password...

So what is causing this weird problem?
Now I have this second user account working, but I want the old one back.
Is there somebody, who had similar issue, and solved it successfully?

Thanks.

Why do you not try it without a password. and see if this happens.

But sounds like you have a TROJAN.

If you do have a Trojan you can register with Avast and get home for free. Then once you have this anti virus installed you can schedule a boot scan. Install program>click run> once it is done scanning your ram you'll get the Avast scan screen in the upper right hand corner their is an arrow click on it and select schedule boot scan> then OK restart. The program will restart and run a boot scan. This has found every virus I have ever encountered. You'll be asked what you want to do with the infected files , put in chest or delete. I always delete them but if your unsure put it in the chest. Fabe Download FREE anti virus software - avast! Home Edition Also if you have an existing AV you have to uninstall it first.

About Antivirs:

I am using Avira Antivirus and Commodo Internet Security already, they are always updated and up, and running.
Commodo have an antivir module too. But neither antivirus program couldn't find anything suspicious.
(Real time protection of Windows Defender is already on, too)

Since safe mode doesn't log you off, try using the MSCONFIG "diagnostic" mode. If that works, use "selective" startup to enable/disable components until you find the one causing the problem.

Now I tried this by unchecking all the items from "automatic startup" tab, except for Avira, and Commodo (I dont think that they could cause the problem, they are up and running in the second user account)

Did not help.
Maybe should I try this with the services tab too? Maybe I have no other choice, so I will try this too...


Addition to the description of the problem:

Now I have two accounts on the logon panel, right?

I click the old one, loading cicrcle appears, then throws back.
When I try again for about 2-3 times, the old account's icon disappears from the screen, and I can only logon to the newly created, second account.
I log off, the game continues.

And weird thing, that lets say 1 try from 10-15 tries is successful, so it doesn't throw me back.

Dont bother with MSCONFIG "selective" startup until/unless you've verified that "Diagnostic" startup does in fact work.

Didn't try diagnostic startup, but with enabling and disabling services I found that windows theming service and the "unsigned themes" service was the troublemaker together.
More precisely a somehow corrupted .msstyles, which was applied before.

When yesterday I used my computer, I edited a downloaded msstyles, applied and forgot about it, because back then was no problem with it.
(after applying I used the computer for some other things, so I didn't remember to this theme-thingie)

When the next day the computer started for first time after applying that theme, the issue was there...
So it seems that reverting back to the orgininally downloaded version of the theme solved my problem.

Thank you all who tried to give me advices, and to help me.

I think this can be marked as solved.
