Database again…??

Sorry for making it an individual request… but as it could be a different problem… here I am…

Posted and received comments all day yesterday. Turned off my PC at night. Open back this morning and it seems that my databases disappeared. I’m unable to access the blog, unable to log in.
The message that appears is

Error establishing a database connection

This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down.

* Are you sure you have the correct username and password? Yes, as I didn’t change nothing
* Are you sure that you have typed the correct hostname? Absolutly, as I didn’t change nothing
* Are you sure that the database server is running?
Here, I have no idea….

If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.

The databases aren’t showing in MySQL Databases, something I didn’t touch since the last upgrade which went very well. On top, I can’t access phpMyAdmin – error #1040 – Too many connections…

Coul it be phpMyAdmin that is at the root of that problem? And what can I do?
