I installed xampp in windows XP. I am able to start apache and tomcat. But when I start mysql, it gets started but stops after five seconds.
So, I am not able to work with PHPMyAdmin.
I checked the mysql_error file inside xampp/mysql/bin and the following was present.

I am using xampp 1.7.7
please help...
i had the same problem and i have found a temporary solution by going to the installation folder
xampp->mysql->bin-> mysqld.exe file
running the mysqld.exe file
my xampp mysql service restarted successfully
I'm not sure if this will also work for your case, but it surely did for me, and I've yet to encounter the answer here.
go to Xampp/mysql/bin/my.ini
add the following line:
innodb_force_recovery = 1
(I think anything > 0 works here, also... it might be handy to make a backup of the file just to be on the safe side.)
You should now be able to successfully start your mySQL service.
This worked for me,
quit the XAMPP
cut the All files in C:\xampp\mysql\backup
paste and replace files in C:\xampp\mysql\data
run as administrator the XAMPP
This is an alternate solution instead of solving the above problem. I think you used windows installer for xampp, instead of that Download the zip file and keep it under c:\xampp. Use this link for downloading in zip format.
http://www.apachefriends.org/download.php?xampp-win32-1.7.7-VC9.zip
If you feel the zip file format is huge. Use 7zip file format.

Earlier I used to have same problem, solved it in this way.
Did you by any chance update your old install and then copy/paste your old 'htdocs' and 'mysql data' files to the upgrade files?
Have just run into the same problem, which I solved by uninstalling then re installing. Copying only my Htdocs over then re building my database... A pain but as I am only in Development and using Symfony2 rebuilding my database with fixtures was pretty painless.
Hope this is of some help.

I had a similar problem that was caused by the TCP port needed for one for the services already being used by another application. In my case it was Skype using ports 80 and 443 as fall-back.
You can check if any of the needed TCP ports are used by another application by running the following at the command prompt:
c:>netstat /a
The offending connection will be listed as "LISTENING" in state STATE column. Then it's up to you to figure out what application is using the port. There is a nice tool called portmon for that.
The ports you'll need are 80, 3360... (anyone can expand on this?)
This is how I solved it:
xampp control panel > config > service & port settings > apache > mainport > 80 (default) change to 81.
open xampp > apache > cnonf > httpd.conf
3 search for ServerName localhost:80 change to ServerName localhost:81 search for Listen 80 change to Listen 81
Start Xampp > apache
whoaa its working
