Hatte zuerst Probleme mit dem Internetzugang. Nach der Systemwiederherstellung kam die Fehlermeldung, dass bcm4sbxp.sys nicht durch die urspr√ľngliche Kopie ersetzt werden konnte und es wurde ein Fehler auf der Festplatte gemeldet. Leider konnte ich checkdisk aber auch nicht starten. Nachdem ich Broadcom 440x 10/100 deinstalliert hatte, wie auf dieser Seite empfohlen, konnte ich checkdisk endlich starten...
