Wampserver icon not going green fully, mysql services not starting up?

mysql apache wampserver

I'm running an application on localhost, it's been running successfully for at least a year now, but suddenly today wampserver isn't starting up. Whenever I rightclick on the taskbar icon and "start all services", it gets orange, but never green. Yesterday there was a data loss problem because one of the mysql tables crashed and had to be repaired, if that's related to this in any way.

If I try http://localhost/phpmyadmin, I get a 403 Forbidden error, which I never got before.

I checked the apache log today and its latest entries are:

Lines 25 and 26 on index_exe.php are simply as below (I was trying to log in to the application): 

$userName = mysql_real_escape_string($_POST['userName']);
$Password = mysql_real_escape_string($_POST['Password']);

Because of the [2002] No connection could be made because the target machine actively (trying to connect via tcp://localhost:3306 error, I figured maybe there's a problem with some other application using the same port, so I tried the following (my wamp is running on D:) :

But now I don't know what to make of this. I made sure my.ini had specified port 3306, and it had (anyway noone changed it in a year how could it suddenly have another value). Any help please! I think Apache is working because when I type in http://localhost, it works and gives the option to go to phpmyadmin or my application folder, but it appears mysql services aren't starting up or something? I confirmed with the admin and no new software (such as Skype) have been installed or anything.

Update

I went to Services.msc and checked wampapache, the status was "started". But wampmysqld had no status. So I right-clicked and chose "Start". A message said "Windows is attempting to start the service on the local computer", but then I got this error: 

Windows could not start the wampmysqld service on Local Computer
Error 1067: The process terminated unexpectedly

What on earth is up? :(

Update 2

I got the mysql working again, here:

mysqld working but wampmysqld not starting up

HowEVER, localhost://phpmyadmin still gives me a 403 forbidden error, and mysql_connect keeps giving me an "Access denied" error.

This happened to me today. Since I had not changed my system setting since yesterday, I assumed it's predominantly a mysql issue on the system. I managed to fix it in the following way.

  1. Open wampserver's mysql log file. This will contain information on why the service threw and error and exited prematurely.

  2. In my case, the mysql service failed to start because it could not read a certain tablespace. The specific tablespace was indicated in the log.

  3. Failure to read such a file could be because of file permissions or the file being broken. In such a case, mysql stops executing in order to avoid damaging a tablespace file that may be linked to a database you need. Usually, if you have a backup of the database, then it is safe to simply delete this problematic file and restore the database once your mysql service is started again.

  4. If you do not have a database backup then you could force the mysql instance to run a recovery by enabling the option in your my.cnf / my.ini file.

innodb_force_recovery = 1

This forces the instance to run the crash recovery.

NOTE: installing a new instance of mysql does not necessarily mean that your databases shall be retained. I suggest you run a nightly backup of your databases if you are working on huge projects.
