Zitat von Niko10

Der PC stürtzt jetzt wieder ab. Ich habe mal mit windows debugger das gecheckt.

Und, welche Erkenntnis ziehst Du aus dem Log?
Du hast nichtmal die Konfiguration des Debuggers im Griff.

Was meint Oracle, oder hast Du garnicht nachgefragt?
Warum sträubst Du Dich gegen eine Neuinstallation ?
Wie lange willst Du noch rumdoktern?
