query never executes in mysql - no error or timeout

Right I have no clue what is going on here. This morning MySQL broke. Running queries in PHP caused my computer to freeze, and running them in phpmyadmin causes nothing to happen. except childishly sim开发者_如何学运维ple queries such as selecting 7 rows from a table. That one runs just fine.

I am going to do a reinstall, but first does anyone have any idea what the problem could be?

Thanks

The MySQL index might be corrupted. Try repairing the tables.
