MySQL help

[Toronto]

well I have wordpress installed, and just randomly it just stopped working. I think it has somthing todo with mySQL database. when I log in to the wordpress, and also when I try to run my site, all that comes up is asian letters and question marks (just text no images)?

I checked my wp-config file everything is right...
and on the MySQL the data is still there...
but under the user (for the MySQL) it says "No Privileges" could that be a problem?
