Vista Log-On Screen Problem

Hi guys. My problem is I cannot passed the logon screen, after typing my password, it will load and then returns again in the logon screen. I tried logging in safe mode, and it works fine. So I remove the password and try logging in again normally, it will return again in the logon screen after loading. I tried the Repair Computer, did not work. It started after my brother installed Red Alert here in my laptop, and additional info , the sound coming from the drive is kinda loud during the installation. After the installation, I reboot and that's the time I was not able to logon. I'm in safe mode now. Please help. Thanks

Welcome,

If it were my computer, I would remove red alert. Although you may enjoy it; will not be much benfit if you cannot use it.

You can try a clean boot, to see discover the cause of the actual conflict.
