HELP! I cannot Log into my account to run a'Hijack This' log

I am NOT able to post the required Hijack This log or any other log. I cannot log into my account. My computor has two admin accounts and two user accounts. I cannot log into any of them. When I attempt a login after several moments it says "saving settings" then "logging out" and goes right back to offering the four icons for logging in. I have rebooted many times including an attempt at a 'safe' boot.
If I cannot login I will not be able to run anything that would allow you to help me so I will first need help in figuring out how to login.

Without logs, there is no way to ascertain whether or not your problems are related to malware or a corrupted operating system. Therefore, since you cannot log into any of your accounts, we would suggest that you post an inquiry at one of the sites that maintains a troubleshooting forum such as these:
