Vielen Dank für die Antwort
Wenn ich auf Logs und dann auf mysql_error.log klicke erhalte ich folgende Meldung:
2016-11-08 23:42:12 1628 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.

InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

Im Windows Event Viewer bekomme ich (neben anderen Fehler die aber denke ich von anderen Programmen verursacht werden) mehere MySQL-Fehler in deren Event-Data Details steht:

Leider sagen mir diese Fehlermeldungen gar nichts.(Ich hoffe das waren die richtigen Informationen
). Ich habe das Problem übrigens auch nach einer Neuinstallation von XAMPP noch immer. Nach der Neuinstallation habe ich nur die htdocs datei die ich mir davor heraus kopiert habe an der entsprechenden stelle eingefügt und nach einem Tutorial den Port verändert, ich glaube aber nicht das es an einem von beidem liegt, da ich den Server auch schon nicht starten konnte bevor ich beides gemacht habe.
