Reinstalling a clean system is probably the easier solution.
But, if you can't do that, then you can list all running services (if 
and only if they support sysvinit tools) with this command:
# service --status-all 2>/dev/null |grep +|cut -f2 -d ']'

Then, just stop services manually, or build a script which stops 
everything except the few services you want to keep alive.
And if you want to have this disabling permanent, then:

$ less /etc/rc$(/sbin/runlevel |cut -f 2 -d' ').d/README

will give you pointers about how to do that.
It is also possible that things starts with cron, so you should 
probably check into /etc/ and /var/spool/cron/ everything included in 
cron's directories.
