MYSQL ERROR .. HELP ME PLEASE !!!

Why Yesterday i can access my db and now i can't ... , it said

1045- Access Denied For User: ;root@localhost' (using password: YES)

Why This Happen To Me ??? :( :( :(

check the user name and password of mysql -- Root Test , Test Test , Root Rufeng , 0 0 etc ..

if you installed wamp or xampp or another software with its own mysql install then it may interfere with your gameservers mysql install. easy way to check is to stop mysql then go into your servers mysql/bin and restart it... if it works after that then you know u had a conflict look to whatever program u installed....if it still doesnt work just remove your "my.ini" (usually in C:/Windows) and then restart winmysqlmyadmin again... you will be prompted to enter your username and pass again (root test) then it will remedy the matter ...

Sorry .. Forget To Post .. Is About .. My Computer .. It's Need To Restart .. Problem Fix ;) ;) ;) Thanks All !! ;) ;) ;)
