Yeah well my computer turns on fine but when i try to logon it will begin loading my settings and then once its finished it just logs itself back off again. I havent the slightest clue as to what it could be... Someone please help

You mean when windows finished loading icons on your desktop and everything then it just restarts?

You need to read and download all the tools listed in the link above, by using another computer and then transferring to the infected computer with a flash drive/CD etc.
